I hit the paper file return and printed. I want to change some input. What do I do?

to resume working on your tax return, you must use the bizarre trick, "Add a State" command.

Go back into TurboTax and change the information and reprint the tax return. If the information just changed on one or two tax form pages, you can go into the Forms (upper right of screen and bring up the individual forms and print them individually.
