We used the desktop version and I have a pdf dated from April 2023 that is the turbotax printout of both fed and state returns. That's what we mailed them recently when he got the letter. That doesn't prove that we filed it, I suppose. (Although how could we get a return without filing?). I have a receipt for e-filing, but it doesn't specify what was filed. Does turbo tax have records of what returns they filed for me using the desktop version? I can see the date/time/amount and which credit card I used, but nothing that says they got my return.
