Completing Entry for K1 Box 20 Z

When running a check on my return I get follow error message:  I need to enter Sch K-1 Partnership (Magellan) Box 20 Code Z info Section 199A income from statement A.  But there is no statement A. The only information supplied by Magellan is supplemental Info for 20Z entitied, "Section 199A Publicly traded Partnership (PTP) $60." 

Frankly, it makes me wonder if Ttax and Magellan K1 interface correctly.  This seems like a trivial entry yet... not what I expect from a quality product.

Looking forward to a prompt reply.
