I live in Pennsylvania. I have a state pension 414H for Box 14. What is the appropriate category drop down selection?

You can enter the dropdown category as Other (not classified).  Employers use Box 14 to report miscellaneous information to employees.  TurboTax uses the Category for specific entries that can affect tax returns.  For example, the 414H is listed for New York because New York has a state tax treatment.  Pennsylvania does not so you can use the Other.

Thank you, now do you happen to know if by doing that it does not add to my gross income?  It is my understanding that that pension contribution does not get included in my annual gross.

You will have to make an adjustment in the Pennsylvania section of TurboTax.  Look for the screen that says Compensation Summary, and click on the Pencil (Edit) next to the W2.  You will see the screen below where you will indicate that you need to make an adjustment.  You will have to enter the amount of the 414H contributions for the exclusion. @njz5012
