"Where did you return the item?" Would this be asking where it got returned to or where the return happened?

For example a delivery package was sent from US to Canada, but was then returned from Canada to US, which would be the answer to this question?

I'm assuming the correct way to ask where the end point is is to add "to" to the end of the question. If I'm right about this, would the sentence in the title be a valid way to ask where the item got returned instead of returned to?

Thanks!
