It may not be recommended to use forms directly, but it is the only option since TT does not correclty handle line 9b of form 8960 otherwise.   But TT will not let me enter data on line 9b directly.  I've tried some various worksheets but that hasn't fixed the error.   Please just answer the question as to how to get TT to accept an entry on line 9b of form 8960. (Or have TT correct its handling of that line).
