Get your taxes done using TurboTax

IRS E-file was rejected twice saying IRS couldn't identify my because the AGI wasn't a match to what the IRS has in their database. I took the number off of the previously filed 2020 return as well as an IRS transcript ( The same number) .  I also checked to see if my return had been filed for 2021 in case someone had tried to file. They show no other return filed for 2021. Is there any other reason why it would be rejected?
