After you file

For my amended return, where on Turbo Tax do I enter the tax paid  with my original return so that it shows up on line 16 of my amended return?  When I go under deductions and credits, I don't see a category for taxes paid by taxpayer, just Payments w/ extension, 2019 refund applied to 2020,  or Withholding not already entered on a W2 or 1099.  Thanks again for your help
