Get your taxes done using TurboTax
In the My Info/Personal Info section, be sure you indicated you 'earned income in another state' and enter Illinois and Indiana.
Are you filing Illinois as a Resident, Non-Resident or Part Year Resident?
If you have the desktop version of TurboTax, go to FORMS and check the Illinois Info Worksheet to see if there are Errors.
Or, Delete the Illinois State Return and step through the IL interview again. To Efile Illinois alone, you may need to indicate that you will 'Print' your Federal return when going through the Efile section. Wait until your Federal return is accepted.
Here's more info on Filing Federal and State Returns Separately.
