K-1 1041 - Interest Expense

Hello!

I finally figured out what to enter for my K-1 1041 form, but getting an error for US source interest expenses for section 14 of the K-1. I only see foreign interest expenses listed on the additional statement, but not domestic interested expenses, so I left it blank. The error I keep receiving is "U.S. source ded-int exp plus foreign interest expense allocated at beneficiary level should not be greater than total interest expense allocated at beneficiary level."

Any thoughts on what I have wrong? Where do I find or calculate domestic interest expenses on my K-1?

Thanks!
