I finally found the answer in another post. The display title on the screen was "capital gains" which I was trying to match to the "capital gains" portion of the 1099. It turns out that TurboTax really meant "capital gains plus dividends" equals the number shown. When I added the capital gains and dividends together from my 1099, that matched what TurboTax was showing when asking about how much of the amount was US obligations. I wish the language was clearer because I kept deleting and re-entering all my investment information thinking there must be a duplicate entry. I even cleared all my data and restarted my return from scratch (federal and state) but no matter what I did, the amounts were seemingly off. Had I known that "capital gains" also includes dividends, I would not have wasted so much time re-entering data.
