mtiemeye - I called ESD and they said they would not give me a number even if I asked. They do not process single-employee corps (I too am an S-corp and the only employee).

Did you make any progress? I have to submit my fed taxes via EFTPS because I can't via Quickbooks. I also cannot submit taxes via Quickbooks. Am considering going to a different software since the functionality I needed is not here. They have also taken functionality away from contractor set-up.
