You do not have to remove the Yonkers information. Just leave it the way it is. All it's saying is that you were not a resident of Yonkers, which is true. It does not mean that you worked in Yonkers.
When you file a New York tax return, TurboTax needs to know whether you were a resident of Yonkers at any time during the year. It has nothing to do with where you worked.
