Even if I didn't need it, it was attached and accepted.
As I suggested in my "possible solution," TurboTax might be creating 2 - Form 7206's. Just delete the one you don't need. I deleted the one associated with my Schedule C because the health insurance I purchase (through my state's marketplace) is associated with the K-1 business, so I kept it. (it is does show as a deduction on a different form.) If you need Form 7206 for Schedule C keep it and delete the one(s) you don't need.
KEY takeaway: Make sure you only have 1 - Form 7206 in your return. Then try filing.
Also, I didn't see 2 - Form 7206's listed in the left side panel, so it was never obvious I had more than one until i did the search, as noted in my first reply. @Deborahwrites1
This might work for some people.
