Gains due to distributions (or loan repayments) > basis have to be entered in the input area to produce F 8949/Sch D (I don't speak PS, I'm a Lacertian).   Not even Lacerte carries the computation from F 7203 to the Form 1040.   

Unfortunately, ProSeries only treats Form 7203 as an informational form to send to the IRS.  It does not "carry" anything anywhere, including not taxing excess distribution and not limiting losses due to Basis.  From a functional viewpoint, is it not functional at all in ProSeries.
