I have an iMac 2017 running Monterey 12.5.1. I have been using a LaCie 5TB external hard drive for time machine backups and my backups were using about 1TB (I had partioned 1TB for storing files leaving 3TB free for new backups). . My internal hard drive became corrupt so I purchased a Seagate 2TB external hard drive and made it my bootable disk and transferred everything from my hard drive which was about 1TB, . I went to check on something and noticed that my LaCie (time machine) was now full with data from 8/24/21 to 9/8/2022 and using 3.8TB.

I know that is a bit confusing. My questions are as follows: 1) should I erase the LaCie and start over with Time machine? 2) How to I direct the time machine disk to backup from the bootable drive and not the internal drive (which is empty).

Thanking you in advance for guidance.

First I would cancel the old existing Time Machine backup schedule. You can erase the old Time Machine backup and then create a new Time Machine backup schedule from the new external disk/OS. When you set up Time Machine you will tell it where to backup to, so there should be no problem or confusion.
