Thanks for getting involved with this thread, Blanche M.

You can delete bill payments by accessing the payments record and clearing it.

Here's how:
 

1. In your left navigation bar, go to Expenses, then Bills.
2. Access the Paid tab.
3. Locate your bill.
4. Click its Show payments option in the ACTION column, then View details.
5. Select Clear Payment, Save and close, then Yes.
   
   

Another option is pulling up your payment or bills record and clicking their More options. You'll see a Delete option which can be used to delete the records.
