Had the same thing happen and called Intuit who said to try putting 0 in the agi field. the steps in turbo tax said my husbands agi didn't match for last year 2018 and I know it does. I guess because he is deceased it causes an issue. The problem is once you go thru the step by step in TT and go back to check not all the steps will show up. It's the part of TT that bothers me. So I'm going to create a new return to look for the agi entry for my husband. If that doesn't work on efile then I'll mail in a return. Just wanted to add what I found out this morning 6/18/20
