After getting this same rejection error 3 times (all filed after feb. 3), I filed with a different service. It seems the issue for me was simply a rounding error through Turbo Tax. Turbo Tax was rounding down incorrectly on line 5 of the 8962 form. When I used the other service, they rounded up (the same way we were taught to do in grade school) and my returns were accepted with no issue.
