K-1 Nothing in Boxes 1, 2, or 3

My K-1 has nothing in Boxes 1,2, or 3 but does have Interest Income (5), Ordinary Dividends (6a), and Other Income (both C and I) and finally Other Deductions (13).    Turbo Tax seems to imply that one of boxes 1, 2 or 3 should have values in them when they ask for Type of Activity.   What am I missing here?
