Thanks for letting us know, @Noxious.
If you are unable to submit your filing through Intuit, you can file directly on the Indiana INTax Web site. If you file the form and have a liability due, you must submit your payment the same time that you e-file.
To log in to the Indiana INTax Web site, you must have your User Name and Password. If this is the first time you've logged in to the site, one of the following is required during the registration process: Federal Employer ID Number (FEIN or FID) or your Indiana State Taxpayer ID (TID).
You can refer to this article to know more about Indiana Payroll Tax Compliance.
