How do I delete a class on the Bank Deposit page?

You can't delete a class directly from the Bank Deposit page, Marcy. However, you can make them inactive by going through the All lists in the settings first.

Follow these steps:

1. At the upper-right, click the Gear icon ⚙︎ and select All Lists. 
2. Click on Classes. Locate the class to inactivate. 
3. Under the ACTION column, click the drop-down arrow beside Run report. 
4. Click Make inactive. 
5. Select Yes to confirm.
