If you edited your /etc/apt/sources.list this is the default. Some sources can also be under /etc/apt/sources.list.d/

It is advised you read the whole page so you understand what is happening. You dont need the mirror section for example.

Sources.list example:

deb http://deb.debian.org/debian trixie main contrib non-free non-free-firmware
deb-src http://deb.debian.org/debian trixie main contrib non-free non-free-firmware

deb http://security.debian.org/debian-security trixie-security main contrib non-free non-free-firmware
deb-src http://security.debian.org/debian-security trixie-security main contrib non-free non-free-firmware

deb http://deb.debian.org/debian trixie-updates main contrib non-free non-free-firmware
deb-src http://deb.debian.org/debian trixie-updates main contrib non-free non-free-firmware

If you want to also download from another mirror at the exact same time so you get concurrent downloads, on a stable release it would be like this:

#Mirror
deb http://ftp.us.debian.org/debian trixie main contrib non-free non-free-firmware
deb http://ftp.us.debian.org/debian trixie-updates main contrib non-free non-free-firmware

A complete file would be similar to this :

#deb cdrom:[Debian GNU/Linux 12.1.0 _Bookworm_ - Official amd64 NETINST with firmware 20230722-10:48]/ bookworm>

deb http://deb.debian.org/debian trixie main contrib non-free non-free-firmware

deb http://security.debian.org/debian-security trixie-security main contrib non-free non-free-firmware

# (e.g. netinst, live or single CD). The matching "deb cdrom"
# entries were disabled at the end of the installation process.

The mirror section is not required and not advised to add unless you know what you are doing. Just putting it out there if you want to test and learn more (which is why we are all here).
