Those articles do not address the issue. Of course everyone knows to enter a correct amount into a box that says "enter correct amount here." The problem is that TurboTax does not use that amount if you have transferred a different amount from last year's TurboTax return when you first started this year's return. See what I am saying? Even if you filed the correct amount, and the IRS has the correct amount, and you enter this correct amount when attempting to correct a rejected efile.....TURBOTAX OVERRIDES THIS WITH WHAT IT THINKS IS THE AMOUNT FROM LAST YEAR THAT IT PICKS UP FROM THE TRANSFERRED PRIOR RETURN. This happens if you accidentally transferred from a return that has a different AGI from what you eventually filed.
I was rejected 5 times trying to e-file the "correct" amount. It was the amount I filed last year and it was exactly the amount the IRS showed in its database. It was the exact amount I kept entering in the "Let us help you correct that" box. The e-file was eventually accepted if and only if I changed the 2018 AGI value that TurboTax was showing on the two tax forms Two Year Comparison and Tax History. This forced TurboTax to change its internal view - the one it sends with the e-file even when you have tried to correct it - to the correct value.
I don't know how else to explain this.
