What should I do about an Ikea tabletop that is allegedly unfinished?

A couple days ago, I purchased a "Gerton" Desktop from IKEA. On their webpage, it says nothing in terms of it being finished/unfinished, merely that you should wipe it down with oil. As I drove it back home, I noticed it had a strong smell that gave me a headache. This furthered my assumption it was finished. However, Googling it for the smell and how to get rid of it, all the posts are about finishing it, either using the IKEA recommended oil or some other type of finish. But I don’t understand why the IKEA desktop would smell so strongly if it was not finished, as it should just be raw wood. IKEA doesn’t have a live chat, PERIOD, and their phone merely gives a robo-message about COVID and no chat agents. Is the wood raw, or is it finished?
