How to disable screen time sharing between MacBook and iPhone?

Usually when I'm trying to look at my screen time for my macbook on my macbook, it will show the macbook screen time and all the time I spent on the websites on the macbook. But for some reason now, it is showing like my screen time from my iPhone. I say "like my screen time" because it isn't showing the accurate screen time from my phone either. For example, it shows minutes from TikTok and Camera which I don't use on my Mac. I don't have the 'Share across devices' on for screen time. I don't know what is going on.
