Schedule K-1 when Box 20 Code Z has no value but there is Section 199A to report

There's another thread marked "solved", but I didn't find a solution that works for me.    I'm starting a new thread, in case my comment on the old thread is missed.

My K-1 just shows "STMT" in the Box 20 Code Z line.  The statement included with my K1 lists a UBIA value. 

If I leave Code Z off of my Box 20 entry, I'm later asked if I missed Code Z, and to answer yes even if my K-1 doesn't have Code Z in Box 20:

When I get to the end of the Federal section, and the software checks for errors, it comes up with one error, this:

I've put 0 on the entry form for Code Z, and tried random numbers as well.  Nothing seems to make this form happy.  I've tried deleting the K-1 for that LLC and reentering everything, but still can't get past this error.

Other conditions that may or may not affect performance are:
This is for an LLC K-1
Income is all real estate rental
Tenant is a business that I own and participate in
Special handling is required
