After you file

If Turbo Tax would have had that option, I would have used it. Had to print and file the extension and mail with a check. There should be no difference in how the software handles putting numbers where they belong on the forms when it has the numbers.

The dollar amount was in Turbo Tax in the box asking what was paid with the extension, but doesn't get entered on the form itself. That's the problem. Turbo Tax had the figure, but there is a software error that doesn't transfer it to the actual document that gets sent to the IRS; that's an important step in the process. I found the same question being asked over 4 years ago. Fortunately someone's response reminded me to go look at the form itself and make a manual entry. The point is, we use Turbo Tax to simplify the filing of our taxes, not make it more difficult. 

I've been doing taxes for myself and a couple others over 40 years. I've used Turbo Tax for well over 20. Software has glitches, it's the nature of it, especially when it's doing complex duties with constantly changing parameters. People who write software need to have these glitches pointed out when they occur so they can be corrected. Turbo Tax doesn't seem to have any process to have this information sent to them-that's a glitch in their process that should be corrected.
