How can I see my various tax forms?

To view your complete tax return using the online editions you would have to pay the TurboTax account fees.

However, you can view your Form 1040 plus Schedules 1, 2 and 3 at any time using the online editions. Click on Tax Tools on the left side of the online program screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

With online TurboTax you do not have direct access to all of the forms.  Forms mode is only in the CD/download.  Before you file using online, you can only see your Form 1040.

Click on Tax Tools on the left side of the screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

You can download and print all the forms but you have to pay the fees first.
