It depends on which program you are using, desktop or online. In desktop, switch to Forms Mode, open your return and select the Forms icon in the top right corner of the screen (or choose Forms from the View menu at top). The 1040 Worksheet will display, and all the forms in your return will be listed. Simply select a form to open it. View Forms in TurboTax Desktop.
In the online program, see the product indicator to the right of your screen name at the top of the question. TurboTax Online does not have forms mode. Forms mode is available only in the CD/Download TurboTax software. In TurboTax Online the only way to see most of the forms is to print your tax return. However, you can view Form 1040 and Schedules 1 through 6 by following the instructions in the FAQ at the following link.
