Spouse's Job Location Closed And Moved To Another State But Allows Her To Work Remotely

My spouse's physical location shut down their office in Georgia and moved to Tennessee. She and her coworkers kept their employment and work 100% from home now. Add on top of this that we moved mid-year to West Virginia where she still works remotely in the job she had in Georgia. 

 

How does this need to be filed? Does she need to file Tennessee, Georgia and West Virginia state taxes? 

 

Thanks
