Hello there, globetreader569.
You can re-enter the IL Account Number and make sure that it follows the format. For example: 12-3456789000 or 12-3456789001 FEIN + 3 digits, usually 000 or 001.
If you are still prompted with the same message, I'd suggest contacting one of our Phone Support Specialists. They have more tools available to check on this further.
Here's a link where you can get our contact information: https://payroll.intuit.com/support/contact/?infosrc=qs&service=64
Feel free to leave a comment if you have any additional questions. Thanks.
