im entering what my w2 says on section 11 for my agi, however turbotax says its incorrect.
i filed jointly with my ex husband in 2023. and for 2024 im filling single head of household with one dependent
Your AGI is not on the W2. You need your 2023 AGI to efile 2024. The AGI is on 2023 1040 or 1040SR line 11. If you filed a Joint return you use the same AGI for each spouse.
If you didn't file 2023 or filed it later in the year or mailed it, then try entering 0 for the AGI. If that doesn't work you will have to print and mail your return.
