If all the investment in your business is from your own money, and if you are liable for any loss from the business activity (i.e., no one else covers the loss), then that would be "at risk".
If it wasn't all from your money and someone else is responsible for all or part of the loss, that means some (or all) is not at risk. If you originally said the business was "NOT at risk", is there a Form 6198 in your list of forms?
Let me see if I can ask tax expert @ DawnC or @ MarilynG1 to assist you on why there is no evidence of a Schedule C in your online forms list and further explain this situation.
