Hate doing 1116 it always needs a bunch of adjustments and clicking around in forms to make it work. I had the same issue and had to write in about HSA contribution and a CD early withdrawal penalty. This is one of those things where TT just gives up what to write probably because of all the different things that it could be, and asks the user to summarize it. The need for the deduction, I think, is Form 1116 does some sort of deduction calculation based on ratio of foreign source income over all income to determine how much of the tax you can claim back from a given country. A lot of gymnastics which just seem overly complicated. I have foreign tax deduction from prior years trapped as a carryover and can never figure out what will release it.
