If you want to review something, you can choose something from the left side menu. After you have paid, you'll also have the option to download a PDF of your return by clicking the Preview button on the Filing Hub page.

Cannot review the tax return before printing 

What is the answer to the above question?

@medwards123 Please open the return from the 'Home Page" and open the return you would like to review. From the left hand side panel go to 'Tax Home' and from there you can select 'Review" option to go through your return.
