I want to go back to federal to review before I file, how do I do that?

To return to the Federal section prior to filing your tax return, sign into your Online account and click the orange button that says "Take me to my return", then go to Federal Taxes at the top. This will take you back to the Federal portion of your tax return. Simply click a section that you want to review and continue through the section until you have finished.

But I cannot see the Federal Taxes tab.  Only the State Taxes tab
