TurboTax Online keeps insisting that I need to upgrade to Deluxe because of medical expenses. I do not have medical expenses to file. How do I resolve this issue?

All I want to do is use the free TurboTax Online product as I have done in previous years. I've scoured my file to try to find whatever checkbox I must have accidentally clicked to imply that I need some extra form not included in TurboTax Free, but I can't find it.
