This error seems to happen most often, but not only, when the taxpayer died during the tax year. All the answers here won't help. We are getting boiler plate responses. I copied the AGI directly from the 2018 IRS transcript and it still said my spouse's AGI didn't match. There's a glitch based on the number of these questions posted on this website. Not saying it's TT, just saying that all of us cannot be entering incorrect AGI info. After three attempts of manually entering the AGI and being rejected, I gave up and went to file by mail. It sucks because you have to attached paper copies of the W-2 and Form 1099-R. I usually just get electronic copies. Now I need paper copies. Grrrrr
