Sign in to your TurboTax account, if
you're not already signed in.
In the 2016 Tax
Year section,
click Amend (change) return.
Note: If you see an orange Take me to
my return
button, you can't amend because you haven't filed yet. Just click or tap
that button to open your return and make your changes.
In the pop-up, click Amend using
TurboTax Online
Click Continue on the We'll help
you change (amend) your return screen.
Follow the on-screen
directions to amend your return.
Don't worry if your refund
drops to zero or does strange things while you are amending. Your
calculations will come out correctly in the end.
When you're done, we'll
provide instructions to print and mail your amended return because an
amended return can't be e-filed.
