However, you are
still able to make changes to the return as long as you have not e-filed or
mailed it.
1. If you don't see
a toolbar, scroll to the bottom of the Home page.
2. Click Add a State
(don't worry, we're not really going to add one, we just need to get to the
right place).
3. On the left you
should see a toolbar.
4. To make changes,
click the Federal section.
5. Once changes are
complete, continue all the way through the interview questions until you reach
the File tab.
6. On this tab you
will choose whether to e-file or mail your return. IMPORTANT:
Once you press the e-file button or place the return in the mail, you
will no longer be able to make changes to it.
Once the return is filed, you will have to do an amendment.
