What should I do about this return?

So, I recently dropped of a defective S3 signa at FedEx for return and refund.

I made sure to pack everything down to the last piece of literature.

Made the drop, no problem. Checked tracking, already in transit.

I go home tonight and see the soundbar remote on my TV stand. Big facepalm.

Will there be an issue for me not including the remote? Is there a way to do an additional shipping to return the remote? Or should I just move on and not worry about it?

Any answer helps. Thanks!
