Schedule K1 form

On my schedule K1 form, it says that if you have numbers on part 3, boxes 1-3, you have to fill out multiple k1 forms on TT. However, on my part 3, box 1, it is a 0. On box 2, it is an actual number (-4000). Do I still have to do multiple k1 forms, including the one for box 1 where is has a zero? Because I have interest income in box 5, when I entered the k1 for box 2, i'm getting taxed twice on that box 5. Thank you.
