Per the guidance provided by Inuit in this online community, rentals marked as "Self-Rentals" will be included in the QBI deduction calculations.  However, I've marked rentals as Self-Rentals in the property type and they do not show up on Form 8995-A. 

What other step am I missing?  The only thing that seems to work is overriding the program to force the inclusion of this activity in the QBI calculation in the QBI Deduction section (near the bottom of Input screen 18).  However, this shouldn't be necessary, per Inuit, as I've properly marked the rental as a Self-Rental.
