The easiest way to remove these unwanted amounts is to delete the dependant entirely. You can always re-add if needed (to claim a tuition transfer for example) but this will give you a clean slate for that dependant.
To delete the dependant using the Easy Step interview,
- From the left side menu, click Introduction and select "Dependants" from the list the appears.
- On the Dependants Summary screen that appears, click Delete next to the name of the Dependant you wish to remove.
- Select Yes when prompted to confirm.
