@VolvoGirl Your recommendation (Did you try entering 0 for the AGI? The IRS took a long time to process 2020 returns. So try 0 especially if you mailed your 2020 return.) has worked for me so far. I DID mail in the 2020 returns, and I just got an email from TurboTax saying "Federal Return Accepted". Haven't gotten State acceptance email yet.
