Where is the iphone backup located in my Mac?

Very helpful.

I'm assuming that I can delete past backups without any potential issue to the new one. Meaning that I will not be preventing the recovery process if needed in the future; I'm not losing key links. Correct?

You are free to manage backups anyway you see fit...

—Key links(?) there is no issue

Anytime you upgrade the iOS from the Mac, it automatically creates a backup, old backups are removed..

You can archive iPhone backups if you want more than one backup.

In order to save drive space recent iOS backs are over-written,  unless you manually alter the name or  from Manage Backups Control click and “Archive” the backup.

iPhone Backups

Finder>Go>Go To Folde, copy & paste:

I have mine on an external drive. Click on Manage Backups… and then Control (right) - click on the backup and select Show in Finder:
