How do you store your Recovery Codes?

I’m genuinely curious about how or where you store your recovery codes. I used to write them in a .txt file, and when I reinstalled the system I would make a backup, but on one occasion I forgot to back it up and lost several codes. Fortunately, I was able to generate new ones

That’s why I started storing the codes in Bitwarden, even though I know it’s not ideal. I’m interested in learning about some alternatives to store them in a somewhat safer way, or at least so I don’t have both passwords and codes centralized
