Two W2's due to overflow causing issues with electronic filing.

I have an additional W2 this year due to an overflow for Box 12. This W2 does not have a value for Box 1 so I left it blank, however at the very end the Smart Check is telling me that because this box on my second W2 is $0 I am not allowed to file my taxes electronically. I have not seen this issue in previous years when I filed with TurboTax and I have had 2 W2's because of overflow before. Does anyone know how to get around this?
