I cannot select TurboTax Free even though I am submitting a simple return. TurboTax seems to think I am claiming charitable donations. I am not and have triple-checked.

I receive the message: "You're almost done! Because your return includes charitable donations, you need to upgrade before we can file." I did not check the box for charitable donations. I submitted a charitable donation last year, so the box came pre-checked, but I unchecked it and have confirmed this multiple times, saved my progress, etc. How can I just submit my complete, simple return?
