Turbotax does not prepare any city taxes, except for New York City, Yonkers, and a few cities in Ohio that are part of a cooperative filing arrangement. Otherwise, your city taxes are your responsibility. It is usually a simple form, but you may of course need to copy certain items from your federal return.
If you filed with turbotax installed on your own computer, only you have copies, your return is not saved with Turbotax. If you filed with Turbotax Online, log into your account, and follow these instructions.
