I'll be more than happy to assist you in recording these transactions in QuickBooks Online (QBO), @DebGer.

If your bank covers the fee for payment that was taken by your supplier, you'll only need to record the NSF charge that was processed. To do this:

1. Click the + New icon and select Expense.
2. From the Payee ▼ drop-down menu.
3. From the Payment account ▼ drop-down list, select the account you use to pay expenses.
4. To distinguish it from other expenses, enter “NSF fee” in the Ref no. field.
5. Under the Category column, select Bank Charges.
6. Enter the amount you were charged for and select Save.

After this, you can now record the bill payment using Pay bills. 

Once the bank fee and the bill payment shows up on the Banking page, you can now categorize and match them to these records.
