It seems like you already tried a lot of the possible solutions and one thing that you could check is, if she filed an amended return for 2024, then you need to use the AGI from the original return. According How do I find last year's AGI? Turbo Tax help article, there are other scenarios that could help you figure out what the correct AGI could be:
- Don't calculate your AGI from your W-2s or 1099s.
- If you amended last year, don’t use the AGI from that amended return. Always get it from the first return you filed, even if that AGI was technically incorrect (for example, if you forgot a W-2).
- If you printed and mailed your return and it wasn't processed by mid-December, then enter 0 for your 2024 AGI.
- If you filed a return last year, but somebody claimed you as a dependent, enter the AGI showing on your return for last year (not theirs).
- If you filed jointly last year but separately this year, enter the AGI from last year’s return. The same goes for recently-widowed or divorced taxpayers who filed jointly last year.
- If you're filing jointly this year but selected married filing separately last year, enter each spouse's individual AGIs from last year. This also applies to newlywed couples.
- If you're a first-time filer over the age of 16, enter 0 as your AGI.
- If you efiled or printed and mailed your return and it was processed after the October deadline, enter 0 for your AGI.
- If you didn't file a tax return in 2024, enter 0 for last year's AGI.
If none of these help, you will have to file a paper return.
