Click on the back button. Then select My Info > Dependants Information. There you can delete any dependants that you no longer need.

When I go back I don't see My Info.  Where do I find it?

It's currently showing I have 18 dependants.

You'll see it in the left side menu ≡.  You may want to try clearing your browser cache (or use a different browser) and try again. If you are still not able to resolve this issue, please contact our phone support team at 1-888-829-8608 for more help.
