I have done all of those steps, and while the TT interview questions show the amount paid with extension as entered, they are NOT flowing through those payments as made on Schedule 3 (line 10 and line 15), and nothing is flowing through to Form 1040 Line 31. So it looks like I did not pay it, even though I mailed in the check and the IRS cashed it long ago. Is there a way to "override" Schedule 3 or Form 1040 to show the amount paid with the extension?
