When I get to step 5, Answer the first question Yes. I do not see a yes or no question, I see my line of work.

And I cannot see where this can be done manually.
In the search bar type, "schedule c" no dashes and the space. It will take you to the form to write off expenses/include more income (you will have to choose each expense category you want) after confirming some information.
