How do I erase old backup files from an external drive?

I use a Seagate external drive to store the Time Machine backups and it is filling up. How do I selectively delete the older files? I tried dragging to Trash but they never finish deleting and stay in the trash bin.

iMac 21.5″ 4K, macOS 12.1

Welcome. Disable Time Machine in System Preferences > Time Machine. Open Disk Utility, select the top level of the drive, click Erase, Settings…

The files in the Trash will be gone once you erase the drive.
