According to Internal Revenue Manual (IRM) 21.4.1.3, standard processing time for electronic returns is 21 days. Your 20-day timeframe is within expected parameters. Treasury Regulation §301.6402-2(e)(1) establishes that refunds must be issued within 45 days of the prescribed filing date to avoid interest payments. The IRS typically prioritizes straightforward returns in the February timeframe to maintain compliance with this regulation. I've documented processing times across multiple tax years and found that returns filed between February 10-20 consistently show the most efficient processing metrics.

Your 20-day turnaround is actually quite good compared to what I've seen this season. My brother-in-law filed on the same day as you and is still waiting, while my neighbor who filed a week later already got his refund. It seems like there's much more variability in processing times this year than in previous years. Last year most people I know got their refunds within a very predictable 21-24 day window, but this year I'm seeing everything from 14 days to 40+ days with no clear pattern based on filing date or complexity.

I'm not convinced transcript updates mean anything definitive. My transcript updated on February 12th with cycle code 20240705, but my refund is still processing 22 days later. The 846 refund issued code appeared but the money never hit my account. Called IRS and they said there's a random review that could take up to 60 days. So transcript updates can be misleading too.

Your situation is different than OP's. Based on the cycle code you mentioned (20240705), your return was processed in the 7th week of the year, specifically on February 16th, 2024 (not 12th). The 846 code indicates a scheduled payment, not an immediate one. For direct deposits, there's exactly a 5-7 business day delay from 846 date to bank receipt. If you received an 846 on February 16th, payment would be sent between February 23rd and February 27th. Today is March 6th, so you should have received it by now, which suggests a specific issue with your return rather than normal processing.

The disconnect between TurboTax's estimate and the actual IRS processing is like expecting Amazon to deliver during a snowstorm just because the app says it's coming today. The IRS batch processing system is handling millions of returns, and tax software companies don't have real-time access to where yours stands in the queue. I'm seeing similar delays across several states, not just Pennsylvania, so you're definitely not alone in this frustrating situation.

I might be able to offer some reassurance. My return had almost identical timing to yours - filed on January 29th, accepted February 5th, and TurboTax estimated February 26th. My WMR stayed on one bar until March 2nd, when it suddenly updated to approved, and I received my deposit on March 4th. It seems that, in some cases, the system might not update until very close to the actual deposit date.

I'm not entirely sure about all options, but... I believe your sister might want to consider using the IRS Free File Fillable Forms if she's comfortable with tax concepts. It's completely free and gives full access to all forms and schedules needed for credits. However, it doesn't provide much guidance, so she would need to know which credits she qualifies for beforehand. Perhaps a middle ground would be starting with a free commercial option like FreeTaxUSA to identify potential credits, then double-checking everything before filing?

Most people probably don't realize that different tax software might give you different refund amounts for the exact same information. It's generally worth trying at least two different services before filing, especially if your sister has a somewhat complex situation. In my experience, FreeTaxUSA tends to be pretty thorough with credits, and they only charge for state filing, not federal. That said, no software is perfect - they're only as good as the questions they ask and how you answer them.

Have you tried visiting a local Taxpayer Assistance Center? They can verify your identity in person. No waiting for letters. Did you receive a CP01 notice? Or was it a 5071C letter? What about the 2022 verification - did you do it online or by phone? Sometimes the verification doesn't fully process in their system.

Omg I'm so angry for you! The IRS is TERRIBLE at communicating between departments! My brother had his 2021 AND 2022 returns held for over a year because of this exact issue. The ID verification department never told the review department he'd verified! He lost his apartment waiting for those refunds. CALL THEM WEEKLY until it's fixed - don't trust that they're actually processing anything!
