While one could make direct entries onto Form 8995 in tax year 2018, in tax year 2019 one could not (?why). Using the override function is never a good option. TT just doesn't like it.
You need to find the correct form(s) on which to enter your QBI figures. For me they were Form 1065 (K-1) and K-1, additional information, sale of partnership interest.
Once you enter these figures on the appropriate forms, the QBI information should flow to form 8995 and the deduction be automatically calculated.
