Thank you for your reply!
That's where I have the problem though; I'm not a resident of NYC or Yonkers. So when I attempt to e-file, TurboTax will not let me proceed with the box being left blank. It's forcing me to the screen where I either (a) correct the issue and fill the box in, or (b) opt to mail the return in.
So right now, it won't let me leave the box blank.
