I totally understand your question because I find the same bug. It took me days (wasting my precious time) to research and try. Same here, my CPA did not use the form 6198. This is an abc topic when a person brings in the 1120S into 1024. So, I try the H&R Block instead. Voila, problem solve!
Turbotax is easier to use in general but after see all posts, now I can confirm that TT is not using the same practice as CPA does in this area which could ruin the whole product. May be if the number bring in from their business software would handle differently?
