Hello rjahn,
When doing an electronic filling for your state tax, you have to do it in QuickBooks. You'll have to enroll in QuickBooks Desktop Payroll Enhance first.
There are requirements upon enrolling to pay and file payroll taxes online. You can follow the hyperlink I have provided to guide you through the steps. Also, take note that form filing and tax payments should be done separately.
For future reference, check out: Payroll Tax Compliance Links.
Let me know if you need further assistance. I'm ready to back you up. Take care.
