Before filing you can preview the 1040 or print the whole return. You have to pay any fees first before you can see all the forms, etc.
Forms mode is a feature of desktop (CD/download) software only. With online TurboTax you do not have direct access to the forms until you have paid all your fees. Until then you can only preview 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.
