I'm getting an error in Proseries when I try to e-file an 1120 extension using form 7004.  Proseries is saying that the form can't be e-filed with zero balance due, it must be printed and mailed in instead.  I checked the IRS website and it does NOT say that at all.  It says that you CAN e-file the 7004, nothing about there needing to be a balance due.  Please look into and fix this error ASAP, since I need this fixed for the 9/15 deadline.
