My Trackpad now shows up as my Google account name?

[Turnpike]

All my devices and iMac are up to the latest software updates. My Google account is say Mr.Google@gmail and my Apple/iTunes/iCloud is say TimApple@icloud and my computer name is Mr.iMac

My Airpods would show up as TimApple's Airpods, my Apple Watch would show up on FindMy as TimApple's Apple Watch, and so on.

But now suddenly my Trackpad which always would show up as TimApple's trackpad now suddenly shows up as MrGoogle's Trackpad.

Does anyone know where I could look for settings on one account or another that the info got criss-crossed or automatically read?


Thanks.
