Hi @jessicaj Have you tried repairing? First step otherwise would be turning Bluetooth off and On followed by a restart to see if that helps at all. if not try resetting the Network connections . Go to Settings-General Management-Reset-Reset the Network connections.
You could try clearing the Bluetooth cache. Go to Settings-Apps, if Bluetooth not visible you may need to tap sort-show System Apps, Force stop and clear Data/cache. After this step advisable to Restart. Some more detail and other suggestions https://www.technobezz.com/fix-android-phone-wont-connect-or-pair-with-bluetooth/

1. Turn off the device.
2. Connect To Computer or plug in USB-C Headphones , Press and hold the Volume Up key and then press and hold the Power key
