IRS rejected my return due to 2020 AGI not matching, but it does match what was submitted in 2020.

I have tried to submit my taxes to the IRS online using TurboTax, but it was rejected due to my wife's 2020 AGI not matching. I used TurboTax last year and it populated the same amount as was submitted on last year's return. I tried to reenter the same number, but it keeps getting rejected. How do you fix this?
