Your 2022 tax return shows your 2022 Adjusted Gross Income (AGI) If you filed a joint return then the AGI is the same for each of you.
Form 1040 line 11
If you are using the same TT account that you used last year, you should also be able to find this number in your Tax Home for 2023
If entering the amount from your 2022 tax return does not work, then try entering “0” instead. If that does not work and you still cannot e-file, then print, sign, and mail your tax return.
