Yes. I don't think it's the IRS. I think TurboTax is guessing at this point. The IRS is rejecting it because they want a value on line 2B on form 8962. TurboTax leaves the line blank if the value is 0. The IRS is rejecting the return (rejected mine twice now) because that field is blank. There is no way for us to correct it other than to print out the return and fill in that line ourselves.
