Using 를/을 있어요 is Wrong | Korean FAQ
This is a super common Korean mistake, and I've seen everyone from brand new beginners to high level beginners make this mistake.
Don't use the Object Marker (을/를) with the verb 있다 ("to exist"). Although it's not quite this simple, otherwise so many people wouldn't be making this mistake. There's a reason why this mistake exists in the first place, and it has to do with 있다 being used to mean "to have."
