I didn't get a rejection code. I got an email saying both federal and state e-files were rejected and telling me to open TurboTax and go to the filing tab to see what happened. I did that. There it said again my e-files were rejected, to check my AGI and try again. No error code. My best guess is that since the IRS has not processed my 2020 return yet, their system doesn't have my 2020 AGI, so their system can't verify the 2020 AGI provided with my 2021 return. Being tax due day, I felt that getting this resolved today was unlikely, so I printed my returns and mailed them before noon. Still, I'm out $25 TurboTax charged me to file my state return electronically, even though it didn't work. I'm in the process of trying to get a refund for that.
