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

1. Open or continue your return in TurboTax, if you aren't already in it.
2. Select My Info in the left navigation.
3. Select the Add a dependent button if you need to add someone. Select 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).
