K1 loss increase my tax?

I have $100 in box 1 and $9000 box 2 , they are both loss. Also $20 in box 5.  Turbox tax said it needs to K-1 since it has both box 1 and box2. But which K-1 should $20 to go with?  after I input $20 as interest, my tax owed got increased and the total $9000 loss didn't increase the tax owed. Why?  Thanks for the replies for the two questions.
