Unable to Electronically Submit Illinois Return Because Form IL-4644 Makes e-file Ineligible

[TonyAIllinois]

I received a message from TurboTax stating my Illinois State return was ineligible for e-file because Form IL-4644 is part of the return. I'm hoping for your comment on the following three points: 1) I want to confirm this is the case; I can't e-file. 2) Also, wondering why this Form makes the return ineligible for e-file. Finally, 3) I don't recall being prompted last year to separately report sales from an employer stock purchase plan on the Illinois form. Thank you.

this is from IL - can not e-file 

if there are subtractions except for social security income, retirement income, Illinois Income Tax overpayment, military pay, or exemptions

the IL-4644 is a subtraction that is not listed above

@Mike9241 - Appreciate the response, however, it's not clear to me "Why" E-file is not an option..

I am having same issue with TurboTax not allowing E-file for Illinois Return when IL-4644 is present.   Could some from TurboTax reply here and provide clear answer to this issue.  Thank you!

TurboTax software does not support e-filing of Illinois Form IL-4644.  See this:
