After you file

So I finally got ahold of the irs, talked to a really nice guy who said there is just a verification delay from one or more of my employers and I just have to wait for them so that the irs can compare numbers and then everything should be a go. I will apparently be receiving a letter on Monday. Does anyone know if there is any way I can expedite this process, faxing in my w2s? Otherwise I’ll just continue this fun waiting game...
