In most cases where the IRS rejects a tax return even though the correct 2020 AGI is entered is because the 2020 tax return that was filed has not yet been processed by the IRS or the IRS processed the 2020 tax return late in 2021 or in 2022 and the 2020 AGI is not in the IRS database.

Special Instructions to Validate Your 2021 Electronic Tax Return
If your 2020 tax return has not yet been processed, enter $0 (zero dollars) for your prior year adjusted gross income (AGI).
