Rental real estate safe harbor. Aggregation of business

Info: I work a W2 job and my husband works our rentals (~20 properties).  Working the rentals (rehabs, make-readies, maintenance) is his full-time job.  In addition to my W2 job I do a fair amount with the rentals also (showings, screenings, move-ins, move-outs, rent collection, books, and field/schedule tenant requests/maintenance). We are sole proprietor.  We/he qualifies as a real estate professional due to the amount of work he does.  We classify as a business or trade and the qualified business income deduction (QBID) based on the IRS guidelines.

 

1. We do not spend 250hrs on each property each year.  Some get more (a lot more) attention than others in different years.  To use the safe harbor for QBID do you need to spend 250hrs on each property or do they need to be aggregated (I did not aggregate last year)?

 

However, aggregation was chosen even though I chose "I elect to use a safe harbor for the property on its own (irs notice 2019-07) on the screen that asks "Do you want to use a safe harbor to qualify this property for a deduction?"

 

This has kicked out the ability to efile because the Rental Real Estate Safe Harbor Statement -199A must be signed and mailed.

Thanks
