IRS says I did not file but they cashed my check....
So I went to efile and got the AGI rejected problem. Sucky since I used TurboTax last year and so I am quite certain I know what my AGI is - but I kept getting rejected on an AGI mismatch.
So I try to get transcripts of my taxes to get my AGI off of that, the by mail method was a bust since they said I had no file for last year - silly. But after waiting for 2 weeks to get the verification PIN snail mailed to me, I can get into my IRS account online. There I see that I have a, not a Tax Return Transcripts, but instead I have a Verification of Non-Filing for last year. Confused, I go back to my checking account and confirm the IRS cashed the check I mailed with my return in the same envelope.... What the Heck!!! I should add that I filed after April 15, and likely just after the June 15th deadline in 2020. my check was cashed on July 29th. I do not know when I filed exactly (it was a year ago...) but the cancelled check has a date of June 22nd on it, so likely around that time.
So now I have 2 questions:
1) What do I put on my return this year for my AGI to allow me to efile, when the IRS wants it to match nothing for verification - since they think I did not file last year.
2) How do I get this straightened out? They obviously got my return. Do I just mail it again? Is there a late filing fee or something? how do I avoid that when they clearly got my return? I would imagine this is far enough out of the realm of the ordinary that I would need to talk to someone at the IRS. Is that even possible?
