Hello there, @chingying2018-gm. 

Thanks for reaching out to the Community. You can locate the Payroll section on the left menu. 

Here's how: 

1. Go to the Payroll menu and select Employees.
2. Go to Employees, then select Run Payroll.
3. Select Preview payroll.
4. Select Preview payroll details or Submit payroll.
5. Select Finish Payroll.

 For future reference, you also want to record payroll transactions manually in QBO. 

 Get back to me at any time should you have additional concerns. I'll be here to help.

You need a 3rd party payroll app to integrate with your QBO.
