I have the same question...how does TurboTax come up with the calculated UBIA number? I'm currently using the MAC version of TurboTax Premier for Tax Year 2019 and am at a lost as to how this number is calculated. This field is found on line 7 of Form 8995-A (Qualified Business Income Deduction) and line 9 of the Qualified Business Income Component Worksheet. There doesn't seem to be a drill down to another form to show data source.
I would really appreciate some help. Thank you!
