That's the exact same problem I'm having. And I believe you're correct that the "Unable to e-file" error is due to the 1095-A error. I've had my taxes ready to submit since 1/28/24 and I'm still waiting for TurboTax to get its act together so I can submit. The irony is that TurboTax sponsored a contest for "early filers" (which I entered because I thought I was going to be able to submit my taxes on the first possible allowed day) and here I am, still waiting on 2/14! I've been using TT for 10 years and I.am.not.happy with them AT ALL.
