You can view your Form 1040 at any time. 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.

yes.  under print, choice preview print copy,  it is not necessary to save the pdf when you view.

To see all the forms you need to pay any fees first with a credit card.
