How do I resolve "Return cannot be e-filed when the sum of Illinois wages plus out of state wages on all W-2s does not equal total wages reported on IL Schedule CR"?

I'm filing an IL resident return and a VT nonresident return. I checked over all of my W-2s, and as far as I can tell, the total wages match on all of them. I've read suggestions on how to resolve this issue on TurboTax and tax support forums, but none of the solutions they propose work for me (like deleting and re-entering the IL return). It seems like this problem can be solved, though, which is why I'm asking here.
