Deductions & credits
Box 18 is on the W-2 see the picture below.
Box 18 shows the local wages, Yonkers and the withholding is box 19. Ok so you did not live or work in Yonkers and therefore will be credited for that withholding back into your NY refund. You must complete the Yonkers Non-resident portion in order to get the credit for the amount incorrectly withheld. You must answer yes I had Yonkers income because according to the W-2 you did. Then follow the prompts. This will resolve your issue.
