Not sure what problem you are having that would prevent you from e-filing your NY return if you e-filed your federal return. You cannot e-file a state return if you mailed the federal return. So provide some details about what happens when you try to e-file NY. But---just so you know--although NY prefers that you e-file, it is possible to mail a NY return.
