I made an extra 2016 1040-es payment of $1000.00 for 2016. Where do I place that on my return?

To enter estimated taxes paid (Federal, State, Local) -

• Click on Federal Taxes (Personal using Home and Business)
• Click on Deductions and Credits
• Click on I'll choose what I work on (if shown)
• Scroll down to Estimates and Other Taxes Paid
• On Estimates, click on the start or update button

Or enter estimates paid in the Search box located in the upper right of the online program screen.  Click on Jump to estimates paid

If it is an extra payment, when you are on the data entry screen there is a button for "enter more payments" (desktop) or "add another payment" (cloud).
