Get your taxes done using TurboTax

I am having this exact issue. I’m printing to file by mail so that my return isn’t late. Even reading that form itself, it’s asks what income you’re deducting it from. That part is correct on my form. Yet TT error says that it can’t be done. I can’t find anything online that suggests that you can’t deduct Marketplace premiums for adult children who are not on your return.
