Business & farm

I’m just wondering if I am able to get some help with a similar situation? I followed the instructions that Patti suggested as far as jumping to the schedule C info, but when I do that it brings up questions about dividends received? I’m just trying to figure out how to enter my expenses that I paid for items when purchasing that I ended up re-selling for profit and received a 1099K for. I am already set up to pay for the self-employed turbo tax online…thanks!!
