I'll assist you in handling a returned check or payment that didn't through inside QuickBooks Online (QBO), @cbcof.
Before anything else, we want to ensure we provide the correct information to help you address your current situation inside the program. Are you inquiring about a check you recorded in the QuickBooks? If so, please be informed a check bounces when your bank account has insufficient funds (NSF) or doesn’t have enough money to cover the check amount. Therefore, your bank will impose an NSF fee or a related bank charge.
To sort this out, you'll want to record the bank fee and void the check since your vendor didn't accept it as payment. We'll outline the steps to get you going:
Access your QuickBooks Online company.
On the left navigational bar, click the Expenses tab and then select Vendors.
Select the vendor you paid.
Find and select the bounced check.
SelectMore and then click Voidfrom the pop-up menu.
Confirm you want to void the check, then selectOK.
Furthermore, here's an article to help you keep track of the transactions you entered inside the program: Run a report in QuickBooks Online.
