1099 MISC

I received a 1099 MISC from the state. I receive a monthly stipend (foster care) for my brother, whom I have guardianship of. I was told that it is not supposed to be taxed. I am confused: why is it taxing me as if I were self-employed when I enter the information? When I enter it, it reduces my refund by over 3k, and I only received 4977.63 from the state. What am I doing wrong?
