Someone on another post shared this workaround, and it works for me (using TT Online)!
Go to Deductions & Credits -> Affordable Care Act (Form 1095-A) -> Edit -> Continue. The problem is the pesky "I'm self-employed and bought a Marketplace plan" box. I unchecked that box. Then I went to Wages & Income -> Self Employment -> Add Expenses -> Health Insurance Premiums and entered the total premiums paid, which in turn generates a CORRECT (hallelujah!) Form 7206 and restores the deduction to Schedule 1, Line 17. And it does not double-deduct (the Turbotax warning not to enter Marketplace premiums in that spot assumes you checked the "I'm self-employed and bought a Marketplace plan" box on the 1095-A page .. so long as that box is unchecked, there is apparently nothing wrong with entering it via Wages & Income -> Self Employment -> Add Expenses -> Health Insurance Premiums.) I did a side-by-side, line-by-line comparison of my prior draft return and the new draft return, and everything is now correct!
This workaround also solved another problem I had. TT was rounding each monthly premium on my 1095-A, and then adding the total of the rounded monthly premiums, resulting in a lost $3 deduction on Schedule 1, Line 17 (the amount was $3 less than the actual total annual premiums). Now that the total on Schedule 1, Line 17 is correct (with that extra $3 deduction), my total tax liability decreased by $1. 🙂
Very happy I can finally file my taxes, just in time.
