How do I enter the amount of taxes paid when I extended my return onto my 1040.

If you used TurboTax to file the extension, the extension payment "may" be prepopulated on your return, but you need to check to be sure you get credit for it.   If your extension payment has not been reported, here are the navigation steps to do so.  You can also go through these steps as another way to confirm it has been reported.

• In the left menu column, click the Federal tab
• Then click the subtab Deductions & Credits.
• Scroll way down on the "Tax Breaks" screen until you see the category "Estimates and Other Taxes Paid."
• Click "Show More" to expand the subtopics, and choose "Income Taxes Paid."  (click Start or Revisit).
• On the next screen, titled "Income Taxes Paid," you should see a category of  "Payments with Extension."  Choose the type of extension payment and click Start or Revisit.

NOTE:  If this is a Federal extension payment,  before filing verify that the payment shows up on Schedule 3, Line 10.   It should also be included in the figure showing on your Federal Form 1040, Line 31.

If you have a state or local extension payment, verify the respective state/local payment shows up on that return, too.

ADDENDUM:

And once you've entered the Federal extension payment, here's how you can preview your Form 1040 and Schedule 3 prior to paying and filing.

• In the left menu column click on Tax Tools, then Tools.
• In the Tools window click on View Tax Summary.
• When the Tax Summary opens, look in the left menu column and choose Preview My 1040. That will show you the Form 1040 and schedules 1-3.

Or we can tell you how to pay your TurboTax fees in advance in order to have viewing and printing privilege for all the forms in your return prior to filing.
