Welcome to FlyerTalk!
I hate to break it to you, but TUIfly does not serve AMS. And even if it did, it does not have an interline agreement with Malaysia Airlines, so you would need a transit visa to enter the Netherlands, collect your baggage, and recheck it with TUIfly. And by then you'd be at risk of not making the connection.
