This is such a helpful thread! I'm also a new small business owner and was completely confused about this exact same issue. Based on what everyone is saying, it sounds like the key is to separate the customer refund (which goes on Line 2) from the processing fee refund (which reduces your expenses). I've been making the mistake of only reporting what came out of my pocket rather than the full customer refund amount. This means I've probably been overpaying my taxes! Going to go back and review my records now to make sure I'm doing this correctly going forward. Thanks to everyone who shared their experiences - it's so reassuring to know other small business owners have dealt with the same confusion!

As a tax preparer, I want to emphasize something important that hasn't been fully addressed yet - timing matters! You should report refunds in the same tax year that you originally recorded the sale, not necessarily when you processed the refund. For example, if you made a sale in December 2024 but issued the refund in January 2025, that refund should still be reported on your 2024 Schedule C to properly offset the original sale from that year. This keeps your records accurate and prevents issues if the IRS cross-references your returns. Also, don't forget that if you're using cash basis accounting (which most small businesses do), you need to be consistent about when you recognize both the income and the offsetting refund. Keep good records showing the original sale date and refund date - this documentation will be crucial if you ever face an audit.

I've been through this exact situation! Had code 570 for about 8 weeks last year and it was torture waiting. What helped me stay sane was setting up a weekly check routine instead of obsessively looking every day. The IRS usually updates transcripts on Fridays, so I'd check then and try to forget about it the rest of the week. In my case, it turned out they were just double-checking my filing status since I switched from married filing separately to jointly. Once they cleared it, I got my refund within 2 weeks. Hang in there - I know it's easier said than done when you're counting on that money!

I'm going through the exact same thing right now! Filed in mid-January and got hit with code 570 about 10 days ago. It's so stressful not knowing what they're reviewing or how long it'll take. I've been trying not to check my transcript every day but it's hard when you're expecting that refund money. Reading everyone's experiences here is actually pretty comforting - seems like most people do eventually get it resolved, even if it takes longer than we'd like. Has anyone had success calling the IRS to get more info, or do they just give you the same vague "additional processing time needed" response?

Just to add to the futures contract discussion - different brokers report futures trading differently on 1099s. Some issue a 1099-B and some issue a 1099-MISC for futures trading profits/losses. If you received a 1099-B for futures, double-check the box that indicates what type of transactions they are. I had this exact issue last year and spent hours on the phone with my broker. Turns out they had incorrectly issued a 1099-B for Section 1256 contracts when they should have used a different form. I had to request a corrected form and amend my return.

I've been following this discussion and wanted to share my experience from dealing with a similar situation last year. The key thing to understand is that TurboTax's prompt to mail Form 8453 doesn't necessarily mean you did something wrong - it's often just their way of handling situations where they can't electronically transmit all the supporting documentation. For futures trading specifically, you really need to determine if these are Section 1256 contracts first. Most regulated futures are Section 1256, which means they get reported on Form 6781, not Form 8949. The 60/40 long-term/short-term treatment mentioned earlier is automatic for these contracts regardless of holding period. If you do need to mail supporting documentation with Form 8453, a copy of your 1099-B with a brief statement explaining the transactions should be sufficient as long as it contains all the information you used to prepare your return. Just make sure to include your name, SSN, and tax year at the top of any attachments. My advice would be to first check your filed return PDF in TurboTax to see exactly what forms were included electronically, then decide if you actually need to mail anything at all.

I'm so sorry you're going through this stress, especially with medical expenses looming! As a newcomer to this community, I've been reading through everyone's responses and they're all pointing to the same likely culprit - the Recovery Rebate Credit on line 30 of your tax return. The $1,400 amount is a dead giveaway that this relates to the third stimulus payment from March 2021. What probably happened is that you or your tax software accidentally claimed this credit even though you already received the actual payment. The IRS has really stepped up their game with automatic matching systems, so they catch these duplicate claims almost immediately now. You should definitely receive that CP12 notice everyone's mentioning within the next few weeks. For your immediate medical bill concern, I'd echo what others have said about contacting your healthcare provider - they're usually very accommodating with payment plans when there are tax refund delays. If you're absolutely certain you never got that third $1,400 payment, you can dispute it, but you'll need solid proof. This community seems incredibly knowledgeable and supportive, so you're in good hands here!

I'm really sorry to hear about this stressful situation, especially with medical bills coming up! As a newcomer to this community, I've been reading through all the responses and they're incredibly helpful. The $1,400 adjustment almost certainly relates to the third Economic Impact Payment (stimulus) from March 2021 that you likely accidentally claimed on your tax return even though you already received it directly. This happens when the Recovery Rebate Credit gets claimed on line 30 of Form 1040 by mistake - it's one of the most common tax errors people make! The IRS has really improved their automated systems for catching these duplicate claims, so they adjust returns automatically now. You should receive a CP12 notice in the mail within 2-3 weeks explaining exactly what they changed and why. For your immediate medical bill concern, definitely reach out to your healthcare provider about payment plans - most are very understanding about tax delays and will work with you. If you're absolutely certain you never received that third $1,400 payment, you can dispute the adjustment with proper documentation, but their records are usually quite accurate. This community seems amazing for getting through these kinds of issues - you're definitely not alone in dealing with this!

Does the 4314c letter mention anything about interest continuing to accrue? I had a similar situation but even after I paid what they initially said I owed, they charged interest for the time they were "reviewing" my documents. Ended up having to pay an extra $287.

I'm dealing with something very similar right now! Got a CP2000 in February for unreported 1099-B forms from my brokerage account, paid what they calculated I owed in full back in March, and just received a 4314c letter last week saying they need more time to review. It's so frustrating because like you, I thought everything was resolved when I made the payment. Reading through these comments though, it sounds like this is just how their system works - payment processing and document review happen in different departments that don't talk to each other. @Giovanni - did your 4314c letter give any indication about whether interest might still be accruing during this review period? That's my biggest concern right now since I see others mentioning they got hit with additional interest charges even after paying the initial amount.
