I am in exact same situation. I tried to eFile first time this year with Intuit and my return keeps getting rejected due to 2019 AGI mismatch. I know I used the correct amount because I have a copy of my 2019 return. The mismatch is because IRS still has no record of my 2019 return online, yet they cashed my check and code on account transcript shows 610 Payment received with return. I also did not receive the 2nd EIP. It's bad enough we have to pay, but to have to struggle and fight to pay is unacceptable. IRS isn't taking calls either, just a recording that says try again later. So it looks like I'll have to paper file again this year, and get put at the end of the line again.
