IRS has rejected my 2019 filing 3 times, saying that my wife’s AGI from 2018 is incorrect. It is correct; verified with turbo tax 2018 file. What do I do now?

[Dfkrell]

They accepted my personal  AGI for 2018, but not my wife’s. We filed 2018 as married, filing sperately, but filed jointly this year.

Shen did she file 2018?  If it was later in the year it won't be in the right IRS database and you should use zero.  Did you try 0?

Be sure to attach copies of your W2s and any 1099s that have withholding on them.  You have to mail federal and state in separate envelopes because they go to different places.  Get a tracking number from the post office when you mail them for proof of filing.
