Two things come to mind

#1 - you need to exclude the military retirement income

As you go through the Louisiana interview in TurboTax, you should come to a screen entitled "Any Other Income Exclusions?" On this screen (see screen shot below), click on 04E as the type of income.

Enter the amount of your military pension here.

#2 - you had some outside income on your federal return

For many taxpayers, their Social Security is not taxable unless they have some "outside" taxable income, such as a distribution from a retirement plan like a 401(k) or an IRA.

Between 0% and 85% of Social Security is taxable, depending on the amount of outside income. Retirees are often surprised that not only do they pay tax on the distribution but they also have to pay tax on part of their Social Security that suddenly became taxable.

This extra taxable income might flow down to Louisiana, causing you to owe tax.
