You'll find the link to Withholding not already entered on a W-2 or 1099 under Federal Taxes > Deductions & Credits > Estimates and Other Taxes Paid. (Click the first screenshot below to enlarge it for reference.)

To enter local income tax not already entered on your W-2 or 1099:

• Open (continue) your return in TurboTax Online. (If your return isn't open, you'll need to sign in, click Take me to my return, then click Pick up where I left off.)
• Click My Account (top right of your screen).
• Select Tools.
• In the pop-up window, select Topic Search.
