What is "TRSCK" on a W-2 form, and how do I classify it per TT's Box 14 Identification dropdown?

[Mikey1]

I live and work in NYC, and have a W-2 I received from my employer, who is based in the city as well.

On my W-2, Box 14 includes three items.

The first is "PFL", which is New York State's mandatory Paid Family Leave. The second is "SDI", which is State Disability Insurance.

The third item is "TRSCK". I have no idea what that is, and Google seems to not know either.

I am going through my taxes now, and TT has asked me to enter a "TurboTax Identification of Description or Code" from a dropdown in order to categorize this TRSCK. I am leaning toward choosing either "Other - not on the list above" OR "Other mandatory deductible state or local tax not listed".

And help here would be appreciated. Thank you.

The employer can put anything they want in box 14 so ask them what it stands for if looking at your paycheck stub doesn't give you the answer.
