I am turning in a MacBook, I need to keep my TimeMachine backups on TimeMachine but want to delete TimeMachine history from the MacBook

Where do you have your Time Machine backups? Are they on a separate external HDD?

Unless your MBP internal HDD is partitioned, with one partition devoted to Time Machine, there will be no 'history' on your MBP.

how to disable the local snapshot:

1.click the time machine menubar icon

2.open TM preference...

3.Option...

4.uncheck the ’create local snapshot‘

This will keep normal (remote) Time Machine back ups on, but disable local ones. It will also delete the current local cache automatically.

or

copy and paste into terminal :

sudo tmutil disablelocal
