My 2018 Section 199A K-1 business is marked no on my worksheet and it should be yes. What do I do?

From which form of entity did you receive a K-1; S corporation or partnership (multi-member LLC)?

If you received a K-1 from an S corporation, the 199A figure(s) should appear on Line 17.

If you received a K-1 from a partnership (multi-member LLC), the 199A figure(s) should appear on Line 20.
