I am not able to select an employee to run Payroll. How to fix this

Hello, @sean98. Let me explain the factors that are preventing you from selecting an employee when running payroll in QuickBooks Online (QBO).

If your employee has not been added to a pay schedule or if their status is inactive or terminated, they won't appear in the list. Let's verify by going to the Employees section.

To start, let's check the payroll schedule. Here's how:
 

1. From the left menu, select Payroll.
2. Head to the Employees section and select All Employees from the Active Employees drop-down.
3. Click Edit from the Employment details.
4. Select + Add pay schedule or click the pencil icon from the Pay schedule drop-down.
5. Once done, click the Save button.
    

Let's head over to the Status field if you still can't see the employee. 

1. From the left menu, select Payroll.
2. Head to the Employees section and select All Employees from the Active Employees drop-down.
3. Click Edit from the Employment details.
4. From the Status field, you'll see if the employee is inactive or terminated.
5. Update the status from the drop-down if the employee you're looking for is not inactive or terminated.
