Can I print my federal and state returns prior to actually filing?

You have to pay or register to print your full return.  You can preview the 1040 and Schedules 1-3 without paying, but you will need to register or pay to print or view the full return.  

You can view your entire return or just your 1040 form before you e-file:

1. Open or continue your return.
2. Select Tax Tools in the left menu (if you don't see this, select the menu icon in the upper-left corner).
3. With the Tax Tools menu open, you can then:
   • Select Print Center and then Print, Save, or Preview This Year's Return to preview your entire return, including all forms and worksheets (you may be asked to register or pay first).
   • View only your 1040 form by selecting Tools. Next, select View Tax Summary in the pop-up, then Preview my 1040 in the left menu. ( You can use this option without paying)
