itch.io

its bought not bout and from your spelling im assuming that you didnt buy among us you probably just downloaded it from a youtube video buy the game dont try to get it for free.

If you scroll to the very top of the page, like I already said, not near the bottom of the page where there's a "buy now" button it should show a banner with "You own this game" and a download button. If it doesn't, you didn't complete the transaction, you refunded the game, or you're logged into a different account.
