Update your estimated tax voucher information by following the steps below. You can't change the amounts directly on the voucher, but you can change all of your income and expenses.
- Login and click Take me to my return
- Next, select Federal Taxes and then Other tax situations
- Under Other Tax Forms click Start or Revisit next to Form W-4 and Estimated Tax Payments
- Next, you'll be able to update your estimated income and expenses for 2017, which TurboTax will use for your quarterly tax vouchers.
Otherwise, you can just print the form and enter the amount you want to pay each quarter. You only need to mail in the voucher if you pay by check or money order. Instructions for paying online are included on the voucher form, here: https://www.irs.gov/pub/irs-pdf/f1040v.pdf
