TurboTax gets no information from the IRS after you file your tax return, and knows nothing about the letter you received.

Letter 21 says they made the changes you requested. Did you file an amended return? Sounds like they are done processing it and you should be getting your refund soon.
Thanks
My question was incomplete and I hit post too soon.
I paid quite a bit in April and was required to pay estimated taxes each quarter and have been doing that.
I didn’t request any adjustments (nor do I even know how) so I don’t know why I just got a notice saying they adjusted as I requested and separately got a refund check for about 10 percent of my amount due last April.
Called the IRS number they provided and after waiting 2 1/2 hours finally got a human who proceeded to transfer and cut me off.
Contacted TaxAudit to see if they could help. They required an enormous amount documentation directly from me even after I authorized and they received access to my returns and further despite their acknowledgement I was not being audited.
Anyway lots of frustration here. I’ll try and call IRS again tomorrow but was curious whether anyone else might know what’s going on.
One thing to check. Was there a penalty on your 1040 line 38? It’s common for the IRS to recalculate it and send you a refund.
