Hi, Turbotax is saying I'm ineligible to e-file an IL part year return with credit for tax paid to other state. I was wondering if this is true and if I have to mail?

The reason for ineligibility I get from Turbotax is "part-year returns with credit for tax paid to other states (schedule-CR) are ineligible for electronic filing". But I called the Illinois Department of Revenue and they said this shouldn't be a reason I can't e-file through a third party tax program like Turbotax.
