In case anyone else is wrestling with this, the solution is, after entering the full K-1 for the business, create additional K-1s under the S Corp name, using the S Corp TIN and going to Section D-1 on each subordinate K-1 to enter property specific information for 199A purposes. Also, do not enter the line 17 QBI info in the main K-1 as it will be redundant, enter the QBI info in the property-specific K-1s.
