Fedex — Clearance from recipient specialized form

Effy provided me with all the forms needed in order to send a piece back and I printed and filled everything as needed, still my shipment status is 1. A specialized form/statement is required for clearance from recipient.
What does this mean? It is coming from Nuevo Léon, Mexico towards New York.
If I need more documents for clearance, let me know what I can do so the process can go smoothly.
