Try this. It worked for me.
Open 2020 taxes.
On top, choose Federal Taxes under the blue banner for TurboTax.
Choose Deductions and credits.
Scroll down like you are reviewing each section.
Stop at Medical.
Choose Affordable Care Act (form 1095-A)
select update.
Inside that, you will find a line with a few words of what you entered for 1095-a.
On the right will be a Delete button that looks exactly like when you were filling out charitable contributions.
Delete and then choose Federal Review.
Hit all the continue buttons until you get the e-file at the end.
It should now let you file.
What a stinky bugger that thing was. I was fuming.
