Reorting a software error for TTax Illinois, Form IL-2210 Penalty Worksheet 1

[Teng0]

I'm reporting a software error for TTax Illinois. In Form IL-2210 Penalty  Worksheet 1, the software has a Qtr 4 due date of 01/17/2022, which is Matin Luther King Holiday. That date is wrong. The due date is 01/18/2022. Due to the error, the software treated a payment on the correct due date and assessed a penalty incorrectly. To fix the problem, I changed my payment date to 1-d earlier.

Update to my post. TurboTax reported to me that the error has been fixed on 3/18/22. The correct due date 01/18/2022 is now used for TurboTax Illinois, Form IL-2210 Penalty Worksheet 1.
