Beginners Questions • [O/S] How to stay on stable and avoid getting on debian testing?

Hello, sorry for the noob question, but I recently installed debian on my work computer. I dont know how it happened, but now it seems i am on "Debian GNU/Linux trixie/sid". I suspect it is because i added "non-free-firmware" or something to my sources.list, which now looks like this:

─────────────────────────────────

My uname -a now says: Linux terje-workstation-debian 6.11.6-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.11.6-1 (2024-11-04) x86_64 GNU/Linux

Im wondering, if i reinstall, how can i make sure to stay on stable, (i guess that is "bookworm" ?) and not end up on testing.

Can i downgrade to stable or do i have to reinstall?

Suddently, nvidia drivers stopped working and i have problem installing nvidia-drivers again, and I suspect this is because of the debian version.
