Thank you so much randomlongid. So glad I found your post. I was unable to file it electronically because of an error in "Box 16 Lines C, I, and J : Partnet level foreign income and expense" (K1P addl info 1 page). I had numbers in "total" "interest and other expenses at the partner level" and assumed they were all US Source (K3 didn't say what the source is for "by partner"), but it kept saying there was an error in foreign column when I left it as 0. It was very frustrating. I saw some posts saying Turbo tax suggested to uncheck box 16, so no K3 needed to be fill out. That's not right!
After reading your post, I manually entered zero on schedule K-3 line C "Gross income sourced at partner level" and then went back to the K1P addl info 1 page, and entered zeros in "Gross income sourced at partner level". Then the error was gone.
Thank you again for your post, otherwise I wouldn't be able to make the deadline.
