Turbotax wants to treat income from 1099-misc as business income (schedule C) but I don't think this is right

I received a 1099-misc from PredictIt, which is a website where you can put money on whether certain political events will happen or not. The only box that was filled in was box 3 for other income, but when I entered it into TurboTax, it opened up an entry under the "Business Income and Expenses (Sch C)" section. It doesn't feel like getting some winnings from what is essentially politics gambling should count as a business, so I was wondering if there was another way I should characterize this income. For instance, when I am prompted for uncommon situations, should I select  prize winnings (I currently have none selected)?
