I am self-employed, with a non-SSTB business that I operate out of my home. In determining the QBI deduction, Turbotax does not seem to include the unadjusted basis of home as part of the UBIA. This part of TT is rather opaque, but I have deduced that the only assets included are computers/equipment. I believe that the percentage of home used as home office should be included in the UBIA. This is important because the total UBIA will affect the phaseout value of the QBI deduction. Is there a way to force TT to do this?
