Indiana (IN) does not tax Section 125 elections contributions. IN Employer Handbook

• An example of compensation that is excluded by the Act is the value of Cafeteria (Section 125) Benefit plans.

Indiana may allow a credit for long term disability premiums. IN Deduction for Long Term Care

If there is no specific code you should check 'Other deductible state or local tax' then watch the questions in the IN state interview.

Also, check the wages in Box 1, of your W-2 and compare them to the wages in Box 16 to see if they match or are different.

Thank you.  What is the Indiana State Interview?  I notice that the amounts in Boxes 1 and Boxes 16 for all of my W2s are the same.  Would this for any reason be of concern?

No, not a concern at all.  It just means that IN basically follows the same pre-tax rules, such as your Section 125 contributions, as the IRS. 

I was referring to the State Tax in TurboTax.  It is step-by-step to make sure you don't miss anything.
