The new cohost you are using should be advising you on this. Part of what you pay them for is their knowledge around how the Airbnb platform works @Shawanna0
You don't have a listing attached to your profile so I am presuming you let your management company set your listing up under their profile .
in which case are there any outstanding bookings with the management company?
your new cohost can show you how to set up a new listing under your profile and add them as a cohost blocking out any dates where you have bookings with the current management company @Shawanna0
