Where can I save the employees supervisor name?

It's great to have you here in the Community, @hr-jmgcontractin.

For now, there isn't a way to save the employee's supervisor name under the Employee Detail section. However, we can add the supervisor's name in the Notes tab. To do that, you can follow these steps:

1. On the left menu bar, select Payroll.
2. Go to Employees and select the specific employee.
3. On the Notes tab, add the name of the supervisor.
4. Click Save. 

On the other hand, I still recommend submitting feedback directly to our product engineers. They may look into this suggestion and consider including it in future updates. Here's how to submit feedback:

1. On your QuickBooks Online Account, click on the Gear icon.
2. Under Profile, select Feedback.
3. Enter your feedback and click Next.
