are you in a rush to file for some reason? there are still more than 3 weeks to go before the return is due so perhaps waiting a little longer is best. if you get the w-2c in time then you save $6 and the need to amend or avoid the need to file an extension. i wouldn't wait til the 18th but perhaps file on the 14th. you never know until the return is submitted whether it will be accepted or rejected.
