@yiozayioza What does not work? It does not matter whether or not a Form 4868 was filed through TurboTax. How to enter the amount of taxes paid with the extension request is the same.
If you are using the online editions and are having trouble using the procedure to enter the extension payment then try this:
Click on Tax Tools on the left side of the program screen.
Click on Tools
Click on Topic Search
Enter federal extension payment. With the result highlighted click on GO.
