To isolate the problem, may I know what specific error message you're getting? For now, I highly encourage double-checking the information you've entered. If there are incorrect details, you can always contact your tax or state agency so they can give you the correct details for the setup.
If everything is right and you're still getting the same issue, I suggest reaching out to our Support Team to check and investigate this further. They have extra tools that can pull up your account securely and be able to help you complete the process.
