@kperlman01 , my apologies I should have pointed out that because "resourced by Treaty " is not very common , the screens and questions thereof are generally focused towards actual foreign source income. In your case you have to treat as if these resourced income(s) actually sourced to foreign country ( Portugal ). Please answer accordingly and it should all work.
My apologies again for not pointing this aspect.
Is there more I can do for you ?
