How do I go back and add a dependent? I haven't filed yet I only completed my taxes and it's ready for print but I did not mail them yet.

If you need to revisit the Dependents section in TurboTax Online, here's what you do:

1. Open your return in TurboTax, if you aren't already in it. (To do this, sign in to TurboTax and click the Take me to my return button.)
2. Select My Info on the left side navigation.
3. Select the Add a dependent button if you need to add someone. Click the trash can icon next to the name of a dependent to remove them (we'll ask you to confirm removing them before we take them off your return).
