I have to say based on everything I've read on this, it is a bug in Turbotax. I had to enter a number less than my total loss from "other income" on schedule C. Once I entered this, it reflected a zero on my QBI Deduction form under the Coop section. I did notice that once I enter a number like this in the worksheet, it changes my 8995 to an 8995-A form which is the more detailed form. Since there is a question for a business that received 1099-PATR which would trigger this (and mine is unchecked) I think that would be the trigger.
Hey Turbotax, if you're listening, I think this is a bug.
