Hi DrPilot,

If you processed payroll through checks, you can delete them, update the bank details in your payroll settings, and recreate the paychecks. However, if it was processed via direct deposit, you will want to contact our QBO Payroll support for assistance.

Delete a paycheck:

1. Go to Payroll, then Employees.
2. Select Paycheck list. Download or copy the paycheck details of each employee for your reference.
3. Select the paycheck(s) you'd like to delete, then select Delete.
4. Select Yes.

Update the bank account in the payroll settings:

1. Go to Settings ⚙, then Payroll settings.
2. Select Edit ✎ next to Accounting.
3. Select Edit ✎ to update the bank account.
4. Then select Continue until you're done.

You can always go back to this thread if you have more questions in mind.
