Can you try to enter 0 for both question 1 and 2 if that is applicable to your situation? Enter 1/2 of the SE tax shown on your 1040 and if it is zero, enter zero. And if you have no partnership income, then enter zero for question 2 also.
Your situation is difficult to solve in this format. It would be best if you can contact support again. They are in a better position to resolve if they can view your screen.
