Thanks for joining the thread, Connie2249.

If your employee lives in California while he/she is still working, then, the employee address should be under California. Thus, it shouldn't be changed to Georgia. 

You may check out this article for more information: Edit or change employee info in payroll. 

Additionally, employee who works at a work location in a state outside your primary work-location state, your employee is subject to work-based taxes (such as state unemployment insurance) in that other work-location state, regardless of where your employee lives. To know more about the multistate employment payroll situations, you refer to this article for further guidance: About multistate employment payroll situations.

Please let me know if you have any other concerns and I'll be here to keep helping. Have a wonderful day.
