Linux filesystem remapping

I have an ssd drive and a internal HD one. I want OS pointing to the home located in internal HD and working files Downloads, Music, Videos, Templates, Documentos etc., locatein the HD. My /etc/fstab was edited and got this form.

#
# /etc/fstab
# Created by anaconda on Mon Jul 1 14:06:56 2024
#
# Accessible filesystems, by reference, are maintained under '/dev/disk/'.
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info.

# After editing this file, run 'systemctl daemon-reload' to update systemd
# units generated from this file.

~/.config/user-dirs.dirs is configured like this

# This file is written by xdg-user-dirs-update
# If you want to change or add directories, just edit the line you're
# interested in. All local changes will be retained on the next run.
# Format is XDG_xxx_DIR="$HOME/yyy", where yyy is a shell-escaped
# homedir-relative path, or XDG_xxx_DIR="/yyy", where /yyy is an
# absolute path. No other format is supported.
#
XDG_DESKTOP_DIR="$HOME/"
XDG_DOWNLOAD_DIR="$HOME/Downloads"
XDG_TEMPLATES_DIR="$HOME/"
XDG_PUBLICSHARE_DIR="$HOME/"
XDG_DOCUMENTS_DIR="$HOME/Documentos"
XDG_MUSIC_DIR="$HOME/"
XDG_PICTURES_DIR="$HOME/Imagens"
XDG_VIDEOS_DIR="$HOME/"

where $HOME is /home/herlimenezes, located in SSD and not as desired in /mnt/8a2135a6-7123-4a03-94dd-26e7ce663204/herlimenezes
As I issued fdisk -l and got this:

I hope that this information is relevant to get a solution.
