How can I see a complete federal and state return before I agree to file? I am not sure I gave all info. Also, I want to know if all my social security was taxed?

You have to pay before they will let you see your return. Once you have paid you can save as a pdf on your computer and look at that. If you have changes just go back into the program, make changes then create a new pdf overwriting the 1st one and keep doing this until you are happy. Then file
