Can someone please tell me what GRNDRA mean on my paystub as a deduction

Your best source to ask is either your employer or your payroll department.

Just a guess, but does it stand for Grand Rapids?   Does it relate to city income tax withholding?

It should also appear in box 20 of your W-2, with the yearly total of Grand Rapids city income tax withheld shown in box 19.
