I had a similar experience with my business return this year. It sat in limbo for weeks until I discovered the issue. Have you checked if your software provider received any rejection codes? Did you verify that all your business identification numbers match exactly with IRS records? Sometimes even a slight formatting difference in your EIN can cause issues. Did you receive any email confirmation from your software after filing?

My return was stuck like this for 5 weeks - no acceptance, no rejection, just silence. Could it be a simple software glitch? Or something more serious with my filing? I finally resolved it last week! Turned out my software had actually received a rejection notice but failed to display it in my account. Once I called their technical support line, they found the rejection in their system and helped me correct the issue (incorrect prior year AGI). Resubmitted and got accepted within hours. Don't wait like I did - be proactive!

Based on the specific dates you mentioned (03-03-2025 for code 520 and 03-10-2025 for code 971), your review likely started on March 3rd. The 971 notice dated March 10th is probably the CP05 Notice that officially informs you of the review. From my experience working with tax clients, these reviews typically conclude in 30-35 days rather than the full 45 days. I would anticipate resolution around April 2nd-7th, 2025. If you haven't received your CP05 notice by March 17th, you should call to confirm your mailing address is correct in their system.

I might be an outlier, but my experience with a 520/971 code combination last year was relatively quick. I filed on January 28th, got those codes by February 10th, and still received my refund on February 27th. It seems that sometimes these reviews are just procedural checks that don't necessarily take the full 45 days. I'm not saying this will be your experience, of course, as each case is different, but I thought sharing a positive outcome might help ease your mind a bit.

Be extremely cautious when encountering these errors. According to IRS Publication 1345 (Handbook for Authorized e-File Providers), SBTPG is required to provide timely access to refund status information. However, Section 7.3 of their Terms of Service indicates that temporary service disruptions may occur. If the error persists beyond 72 hours, document all attempts to access your account with screenshots and timestamps. This documentation may be necessary if you need to file a complaint with the Consumer Financial Protection Bureau under Regulation E for delayed access to funds.

Just wanted to share a success story! After getting the same error for 3 days straight, I tried accessing SBTPG at exactly 4:30am this morning and got right in! The website shows much less traffic during early morning hours. According to https://downdetector.com/status/sbtpg/ the site has been having issues since Monday with peak outages between 9am-6pm. My refund was there waiting the whole time! Try again during off-hours and you'll likely have better luck.

I'm honestly a bit skeptical about the advice that H&R Block gave you. 🤔 In my experience working with tax situations, an amendment - even one with $0 adjustment - still goes through the amendment processing system. The 21-day timeline sounds like they're just quoting the standard refund processing time, which doesn't apply once an amendment is filed. I'd prepare yourself for the longer timeline, just to be safe. If it comes earlier, great! But don't count on it.

I think we need to consider that this might be a special case since it was the tax preparer's error and not an actual amendment request from you. If you compare this to situations where someone deliberately files an amendment to make changes, those naturally take longer because they require review. But in cases like yours where it's clearly marked as $0 adjustment, the IRS might have a different process. It's similar to how banks handle erroneous transactions differently than regular ones.

I think... there might be a delay with SBTPG processing right now. My DDD is also Feb 23, and I'm still seeing "account not found" as of a few minutes ago. Last year, my account appeared in their system about 48 hours before my DDD, so this seems unusual. Perhaps they're experiencing higher volume? I'm hesitant to call TurboTax again since they weren't very helpful the first time.

I've been tracking this issue for several tax seasons now, and there's actually a pattern to how SBTPG handles these early refunds. In most cases, they seem to wait until they have confirmation from the IRS that your refund is actually being sent before they create your account in their system. For February DDDs, they typically receive batch confirmations from the IRS 24-48 hours before the official DDD, which is why many people see their accounts appear in SBTPG's system the day before their DDD. The "up to 5 days early" is technically possible, but in practice, it seems to happen rarely and might depend on your filing history, refund amount, or other factors that SBTPG uses to assess risk. I would expect your account to appear in their system by tomorrow evening.
