OK, I tried what you did. I took the zero I had input for line 2 out. I then let TurboTax fill in line 2 with the same amount that was on line 1. And that did work OK. However, I used to have a zero on line 2 and that would work OK also so there was a programming change made. And, like I said, my 2019 return has a zero on that line.
Personally, I think the programming change has made input a bit counterintuitive now. A person unfamiliar with the simplified method may leave line 2 blank, then see it fill in with the line 1 amount as they move to the next input field and then think "I guess the taxable amount has been determined now". Inputting a zero kind of forces the issue if you will. But that's just my opinion. I appreciate your assistance on this matter.
