My recommendation is to request a transcript. I took my 2018 AGI directly from my 2018 tax return and got reject alerts. When I went to irs.gov, to look at my AGI, it was different than on my tax return. I had an accountant do my 2018 taxes and submit them electronically, so I have no idea how my AGI increased by over $1300. Anyway, don't trust your tax return; trust what the IRS has in their archives.
