If the vehicle isn't being driven then you don't have to insure it. However, Florida
requires any registered vehicle to be insured
so you may need to suspend the vehicle registration as well if you decide to remove it from your policy. I would recommend contacting the registration office for more information on that. If you do decide to fix it, or if she ends up getting a different car, you simply have to contact your insurance provider to add the vehicle back to your policy. Make sure, however, to not remove your daughter from your policy if she is going to continue to drive other vehicles.
