Where do I show I filed an extension form 4868 and Paid $10,000 for my 2024 taxes?

You do not enter anything on your Form 1040 about having an extension.  If your extension was sent and approved, then the IRS already knows about it.

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
