On your K-1 , line 4 is guaranteed payments.
This line is automatically incorporated into the Qualified Business Income calculations.
Section 199A Information, Box 20, Code Z is informational only. It provides some additional information that you may or may not need for your taxes
Health insurance premiums paid for at the entity level are guaranteed payments, and the accountants filling out the K-1 should have included them in the line 4 number. You do not need to add this number in the 199A section.
(this is what it was for me, it might be possible to be different for someone else)
