City tax is not on your Form 1040. Your Form 1040 is for your federal tax. What are you trying to do? If you have a city tax it might be included with your state program, depending on your city and state.
TurboTax only prepares a few city or local tax returns as an extra step in your state return. For most local tax returns you are on your own. You may have to ask around amongst your neighbors, etc. to find out if you have a local tax and how to pay it. “Google “ local tax for your area. Call your city government, etc. Your only record of paying your local tax will be your own bank/credit card records
