On the Indiana State form, Turbo Tax is saying I need to fill in the "Sch IN-W: Col D-State Income. What is this, please?

[JamesG1]

Indiana Schedule IN-W reports income and taxes withheld.

The Instructions state:

If you have a withholding statement that withholds tax for multiple Indiana counties, enter the Indiana state income and Indiana state tax withheld once for that statement. Do not duplicate the Indiana state income and Indiana state tax withheld on multiple lines.

Instructions for the form may be found on page 35 of the Indiana 2023 IT-40 Full-Year Individual Income Tax Booklet.  See link on this page.
