Isn't this a BUG with Turbo Tax? Shouldn't it list US as one of the Countries? I too have received a K-1 with box 16 checked and a K3 with only US sources and a column A which is the only one containing any values.
Turbo Tax not offering a US option in drop down makes this difficult to map to. Sounds like the way to proceed is to not check that Box 16 in Turbo Tax though it is checked in the K1 I received?
