I don't know the "why", but I can tell you how to check and properly report your extension payment. When you report a Federal extension payment, it should show up as part of the figure on the Form 1040, Line 31, which actually flows from Schedule 3, so look at Schedule 3, too. The extension payment should show up on Schedule 3, Line 10 before it goes to Form 1040, Line 31. Here are the navigation steps in Online TurboTax: Open you return interview, and In the left menu column, click the Federal tabThen click the subtab Deductions & Credits.On the "Tax Breaks" screen scroll way down until you see the category "Estimates and Other Taxes Paid."Click that to expand, and in the list of subtopics 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.Enter (or confirm) the figure for your extension payment. 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 respective return, too.
