Should I fill the 2023 Montana Amounts?. By default the system is showing me that, the adjusted gross income and negative taxable income are filled with zero

Are you filing a Non-Resident or Part-Year Resident return to Montana, where some of your income would not be taxable in Montana?  If you can clarify with more details, we'll try to  help.

Here's more info on How to File a Non-Resident State Return and How to File a Part-Year Resident Return.
