I saw some people debating about gross or net but, when you certify, the website specifically asks about self-employed GROSS income.
Yes. As a contractor your gross income is in fact total revenue - total expenses. The income you would legally report would be the same amount you use to calculate quarterly tax payments. Since this is the first time ever that a contractor could receive unemployment you should definitely use the same calculations otherwise you could, in theory, receive notice several months from now that you were "overpaid" and then be expected to immediately return hundreds or even thousands of dollars to TWC. I wouldn't take that chance.
