I honestly don't know how I managed finally to get it right. If you click on the contributions for standard deduction takers (12b), there is a box where you can add details of the contributions and it has a check box for the option to NOT print if you don't want them to show. I originally had details in the regular place for contributions and then in the 12b detail, but once I had gotten it to behave properly for the amount (for us only $425 this year) by a sort of hit or miss process of deletion and correction, I didn't want to mess with it further. It now has the correct amount both in the 12a box and 12b boxes.
Call me cowardly, but my aim each year is just to what it takes to complete my family returns correctly with as little grief as possible. My spouse wants me to "just go back to pencil and paper", but he hasn't done a return for the last 30 years, so what does he know? : )
