Hello -
I was having the same issue and was able to resolve via this detail. In p.4-5 of the 1065 there is a section for Partners Liability Smart Worksheet. In that section a letter was assigned to the liability amount that was creating the error (in my case "A"). When I returned to the "Sch K-1 Wks" section, I entered the amounts for each partner in the "By Amount" column by the letter A, and it all worked!
