If you have not
mailed your forms, you can indeed to 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 or State Taxes tab and this will open the federal return so
you may add your information.
