The total appears under "Estimates and Other Taxes Paid" on the "Deductions and Credits" page, but I am unable to track it down so I can delete it. "Update" doesn't show it.
Yes, you can. To make this adjustment in TurboTax Online:
From here, you should be able to make the changes you're asking about.
Wait, are you using the "Online" software, or the Desktop/download software??

IF you are actually using the Desktop/download software, then the $$ that shows up on the main menu page for "Other Income Taxes".....that number also includes both state and Federal withholding showing on any tax forms you entered in the Federal Wages&Income section (and a few other possible things) So the "Other......." $$ amount may not be anything you entered within that menu line itself.
IF you are using the Desktop/download software on a Windows computer, you can click on the number on the main menu screen and see what it includes.
