Question about extra package

(New to flex) I just finished my route but when I arrived at the last location I didn’t have the package wasn’t scanned in and I also had an extra package that wasn’t meant for me (that it did let me scan at the warehouse lol)

Anyways they want me to bring it back today because it was a fresh order the support told me to message back after I drop it off at the warehouse for compensation.

Anyways I looked it up and it seems like I won’t get compensated and my account might even get dinged what should I do next time? Make sure all the address are correct on my itinerary ig? Should I be worried?
