Many thanks for your answer, but I have now tried for many hours to play with the entries by for instance omitting the QCD but I still can't get any amount to show on line 4b as taxable income. I tried to override and enter the amount directly but it seems that overriding is no longer feasible. I also compared to 2018 which was working correctly and while the input are exactly the same after I forget about the QCD, it does not work for 2019. Any suggestions? Thank you.
