Retirement tax questions

Thank you. Good to know it. I entered one set with NYC code, and the other one right beneath. Now I have questions as I continue, "Which Locality was New York, NY of $(box19) for?". I have to choose either New York or Yonkers. Same question comes next, "Which Locality was Yonkers, NY of $(box 19) for?" Shall I choose "New York" for the first question and "Yonkers" for the next question? Both in the box 20 say "RES" on W2.
