You need to remove a return from TrustFile.
- Log into your TrustFile account
- If you have the Accountant version, select your company
- You should see the various returns under your account, click on the State Settings link
- By the setting 'If you do not file tax in XX you can disable this state', click the sliding button to disable the return
NOTE: If you should end up re-enabling a disabled state in TrustFile, you'll need to ensure you select your proper form and frequency again, as disabling a state acts as a refresh for all state settings.
