I did my 2019 taxes with the desktop version of TurboTax Premier 2019 Mac. I'm trying to do my 2020 taxes with the desktop version of TurboTax Premier 2020 Mac. In 2019, I had some 1099-INTs for which I used the Supporting Details feature to sum the interest from a few accounts at the same institution. When I imported the 2019 tax file into the 2020 software package, it created the 1099-INT forms with the Supporting Details forms and blanked out the amounts on the Supporting Details forms. All that is expected and fine.
The problem is that since there are no amounts on the Supporting Details forms, TurboTax put 0.00 on the 1099-INT forms and since there is a number there, TurboTax thinks that those 1099-INTs are finished with no errors - so I'm not warned that I have to go back and put dollar amounts on the Supporting Details forms.
What I wanted was to have the missing dollar amounts on the Supporting Details forms propagate to a missing dollar amount on the 1099-INTs, so that TurboTax would warn me that I haven't finished that 1099-INT.
In the absence of that behavior, is there some way that I can manually mark a 1099-INT as "Incomplete", so that TurboTax will warn me if I try to file the return without putting dollar amounts on the Supporting Details forms?
