When trying to pay using a credit card for filing the state taxes electronically, there is a bug in the system which will not let you use a credit card expiration month of 12. (I think this may have been an issue last year as well as I read a post that said you also could not enter months 9, 10, or 11 either). I was fortunately able to finally enter my payment with a card that had an expiration month of 8 which it accepted. Once the state filing fee paid the returns were E-filed simultaneously for federal and state. No idea why the expiration month wouldn't work from the drop-down menu and you cannot override the drop down to enter it manually either, so frustrating.
