Filed my 2023 taxes yesterday, and when asked the AGI for last year's return, I entered the amount in the AMENDED 2022 return that I needed to file.
My 2023 was swiftly rejected because of this... Searched this community and realized that the IRS was expecting the WRONG AGI, from the initially submitted 2022 return, instead of the final, correct value in the amended return.
TurboTax handled this very well; as soon as I ran it, it quickly identified the issue, but instead of asking for the 2022 AGI from our initial joint tax return, it very specifically asked for my wife's 2022 AGI. It just does not make any sense to ask for an individual's AGI if a tax return was submitted jointly, right?
This should be fixed, as it was initially very confusing.
If you filed a joint return for 2022 the amount on line 11 of your 2022 Form 1040 is the same amount for each spouse. Whatever you entered for your own AGI is also to be entered as your spouse's AGI. If you amended then the AGI might not be in the system. When you encounter problems with AGI, always try using "zero" to see if zero will let you e-file.
