Time machine full : oldest files not deleted

Catalina OSX says time machine is full so backup fails. I think It's not deleting oldest files.

Time machine has 2 GB and the unique MBP device, which is using TM, has 512 GB disk.

Suggestions ?

Time Machine removes the oldest qualifying backups but does not ransack the backups attempting to remove as much storage as needed to achieve the current TM backup. Although the size of your internal drive plays a role in the initial capacity planning for TM drive size (2.5 - 3x), it is what has changed on your Mac since the last successful TM backup that determines whether the TM backup can succeed with the remaining storage on it.
