Am I REQUIRED to buy your personal business product to literally claim ONE expense????

I took a side job of $1400. I have a 1099. It cost me $610 in materials (I have receipts) to do the job. When I entered the $1400, (my taxes were complete when I entered) it took $600 from my fed/state refund total. I have literally LOST money on this deal, and turbo tax wants me to pay an additional $90 so I can put my ONE expense in.
