Please read carefully. I am very familiar with filing separately on the combined Iowa form. That is not the issue. On the TurboTax screen there is one box to fill in. Plus there is a total that can't be changed. The prefilled fixed amount says "total" and has $340 in it. The total was $790 not $340.
It doesn't say "Spouse" and "Yourself". One of the boxes says TOTAL. The total was $790. That is not subject to debate. It's what was on my 2019 return filled using TT. The other box has my spouse's name. The TT form asks me to enter what portion of the total is attributable to her. If the total is incorrect - and it is incorrect - then it doesn't matter what I enter for her, it won't fix it.
