After getting an error message saying "Unable to create FedEx shipment. RETURN_SHIPMENT is not allowed for the origin/destination pair. (RETURN_SHIPMENT)", I did some research and finally messaged ShipStation support. Their representative told me to try adding a shipper email or to try any other FedEx service.
In case you have the same occurrence, the only one that worked was FedEx Ground.
