@expat-allover , my apologies for getting the wrong end of the stick. Since I am unfamiliar with working of thew on-line version(s) of TurboTax ( even though it should pretty similar to the windows download/CD version), I will ask my colleagues whom are familiar with that product for help
For both 1099-INT and 1099-Div, there is no general way to declare the income as foreign source , but there is a dedicated box for foreign tax paid. The only way to declare passive income as foreign is on form 1116.
You are welcome to PM, if you have specific questions on the law/ statute and interpretation thereof . I cannot help on the product and/or entry screens for TurboTax On-line
