On the Billing page of a Customer Account, find the Charge (i.e., Tuition, fee, etc.) you need to delete on the Transaction History.
Click the three dots (to the far right) on the Charge, then click Edit:

In the new window that opens, click Delete transaction to delete the transaction (Charge):

NOTE: Be careful before deleting a Transaction in the Transaction History. If you accidentally delete a Transaction and have to add it back, it will be added back with the date you added it, NOT the original date.
Enrollsy also cannot change this date. It is the date a Transaction happens.
