When I filed extension in April, I pre-paid $5000 for federal and $3000 for state taxes. My extension and pre-payment were via TaxAct. How can I apply this to TurboTax?

When you requested your extension you were supposed to pay your estimated tax due.  Did you enter the payment you made into your tax return? 

Go to Federal>Deductions and Credits>Estimates and Other Taxes Paid>Other Income Taxes

To enter the amount you paid with an extension (including state extension)  go to

Federal Taxes (or Personal for desktop H&B version)

Deductions and Credits

Then scroll way down to Estimates and Other Taxes Paid

Other Income Taxes - Click the Start or Update button

Next page second section Payments with Extension

Either Visit All or Click Start or Update by the extension you paid

Be sure you picked the right state in the drop down box and Pay attention to which year you are entering for a State Extension payment.  A prior year state extension payment is also deductible on the federal return so be sure to enter it here.

To get the amount paid on a state extension to show up on the state return……

When you are done updating your federal return, you need to transfer the new federal information by going back through the state tab and the state return. Nothing will change until you transfer the fed info to the state again.
