Turbo-premier K1 box 5. I entered K1 interest. Turbotax asks right below : "Interest from U.S. Obligations in box 5" What is this? it is not on form k1; what/where?

i have interest and put it in box 5 as usual.  what does the question for US Obligations mean and where is it used?

Same question for Box 6B as it also asks for amount US Obligations under entering the Qualifying dividends

i don't remember these two questions and their impact
