After you file

When you prepare your 2020 return, TurboTax will automatically calculate your 2021 estimated tax payments and prepare 1040-ES vouchers if the program thinks you may be at risk for an underpayment penalty next year.

However, you can also calculate your 2021 estimated taxes and generate the payment vouchers by doing this:

  1. With your tax return open, search for 1040-es (be sure to include the dash) and select the Jump to 1040-es link.
  2. Answer No to the question Do you want to change your W-4 withholdings for 2021?
  3. Answer the questions about things like your 2021 filing status, income, and deductions.
  4. Eventually, you'll come to the Print Vouchers? screen. Answer Yes and the program will include your 2021 1040-ES payment vouchers when you print a copy of your return later.
