My returns have not been filed yet but I need to make a correction to them. I don't need to amend, as they have not been filed but how do I correct them?

If you HAVE NOT filed, please follow the instructions below: 

If you have not mailed your forms, you can indeed go back and make changes to the original return and not have to wait to amend.

Please go back to Turbo Tax and click that you need to either amend your return or to add a state.  You do not actually need to complete either of those, but if you select one it will open your return back up for editing.  Go to the top and click on the Federal Taxes tab and this will open the federal return so you may add your information.
