The mysterious AGI mismatch error is a long-standing issue with TurboTax that goes back many years.
TurboTax refuses to admit there is a problem.
If it was rejected for AGI—-be aware that many 2020 returns took so long for the IRS to process that your 2020 AGI might not be in the IRS system. Try using zero instead.
If filing with zero is rejected then file again but select the option that you did not file last year. The IRS does not see that question and it will allow you to e-file with no AGI question.

If that does not work and you still cannot e-file, then print, sign, and mail your tax return.

Thanks. We came to the very same conclusion. Ugh. Now for the penalty phase....
I had a rejection (to an extension) due to "R0000-679-01 - 'PrimaryPriorYearPIN' or 'PrimaryElectronicFilingPIN' or 'PrimaryPriorYearAGIAmt' in the Return Header must match the e-File database." Did you get a similar error message? https://ttlc.intuit.com/community/taxes/discussion/will-turb[product key removed]t-my-payment-for-a-rejected-extension/00/2715796
