Hello there, @Test2Go. 

Direct deposit paychecks can be canceled up until they start to process. We process paychecks two banking days in advance, at 5 pm PST (Pacific Standard Time). For example, if you've scheduled an employee's paycheck on Friday, you can cancel it until 5 pm PST Wednesday. 

If it hasn't been processed yet, you can delete the paychecks:

1. Click Workers, then choose Employees.
2. Click Paycheck list under Run payroll.
3. Select the check to be deleted, then click Delete.
4. Click Yes to confirm the deletion.

If you can't delete it, you can contact payroll support for assistance. Here's how:

1. Navigate on our website: https://payroll.intuit.com/support/contact/?infosrc=qs&service=64.
2. Choose Intuit Online Payroll.
3. Under Free Live Help, get the number for QuickBooks Online Payroll.

I'm still here if you have other payroll concerns though, just leave a comment below.
