@Polkadot1 - I agree that the *result* of the error is that you'd end up not getting the credit you should if your income is over that 400%, but the reason is not because that portion of the form is using old rules - in fact from my view that part is working. Specifically 8962 line 7 show the "figure" of 0.085 - which is correct. The problems is that Line 11A and 11B is not transferring from the 1095A form, but 11C is. What this does is indicate that you got a premium tax credit, but there is no 2nd lowest cost silver plan amount to subtract against the premium credit - which would be shown on line 24 and 26. In my mind TT didn't go back to some old rules/form from years past, this is just a logic error on the form - a bug.
With all this trust is diminished for me - do I need to know all the rules and check every form, every calculation?
