Thank you for the prompt and thorough response. A bit to think about here.
To confirm, I did enter 4 Estimated Tax Payments for the Illinois return. The running Illinois Tax Refund amount at the top of the screen included the 4 estimated tax payments.
When I click Forms to understand the unexpected Tax Liability Balance being presented, I see the Tax Liability, all Payments, and an Overpayment amount. There is no explanation or context provided for the displayed Tax Liability amount. Thus, my original post.
The Underpayment Penalty screen seems to be following the logic of IL-2210 form which initially calculates a lability not including estimated tax payments. (Line 5 result.)
I am of the strong opinion this screen needs improvement such that direct support and explanation is provided for the displayed Tax Liability amount, so the user doesn’t have to wonder and calculate like me.
Thanks.
