Retirement tax questions

I believe you are referring to this screen that says Pennsylvania needs to get specific about what type of retirement income you are receiving:

There are numerous options to choose from. Many plans are traditional or ROTH IRA's, for which there are two choices, one for age of under 59 1/2 and one for over that age. One of the options mentions a state government and another mentions military pensions. You would have to read each option and decide if it applies to you. You can choose the first option [No Entry] if you don't think any of the options apply to you.
