Deductions & credits

Hi, We received a 1099-MISC from the agency for $3200. When I enter it into the "self-employment income and expenses" do I have to put the gross amount of $3200 or the net income? I added all of the possible deductions, but with the calculations made by the website, it's still a huge amount of taxes for how little money we actually make after expenses. How should I enter that on Turbo Tax and not pay taxes on the money we spent on the student?
