TT flags multiple sources of foreign income, prescribing separate worksheets if income is reported in Blocks F, G, & H. My K-1s contain income in only one block.

unfortunately, changes in the tax laws have created multiple sub-categories of foreign source income that TT can't handle.     for example section 951A FTC that can be related  to income reported in a box other than 16.  tt says not provided for in program.
