Disk Not Listed In fstab

some time ago I installed ubuntu 20.04 to my laptop. I believe that I used the default options for mounting partitions. I am now having trouble understanding how it is set up and I would be grateful for some help.

Here are the contents of the fstab file:

# /etc/fstab: static file system information.## Use 'blkid' to print the universally unique identifier for a# device; this may be used with UUID= as a more robust way to name devices# that works even if disks are added and removed. See fstab(5).## <file system> <mount point>   <type>  <options>       <dump>  <pass># / was on /dev/nvme0n1p2 during installationUUID=e19799b8-02b4-470b-ab41-97ac0f760845 /               ext4    errors=remount-ro 0       1# /boot/efi was on /dev/nvme0n1p1 during installationUUID=50D6-96DC  /boot/efi       vfat    umask=0077      0       1/swapfile                                 none            swap    sw              0       0

When I run the Disks utility, it indicates the presence of 2 disks: 1) 256GB flash drive 2) 2TB SSD.

The 2TB SSD does not appear to be listed in the fstab file, though it does appear in Thunar at /media/erik/0d210810-0cf4-48f3-ba54-47a08261c8e5/.

The information displayed in the disks utility includes the following:

Contents: Ext4 (version 1.0) — Mounted at /media/erik/0d210810-0cf4-48f3-ba54-47a08261c8e5

If I click on the gear icon and then "Edit Mount Options", it displays a screen which lists information including:

Mount Point: /mnt/0d210810-0cf4-48f3-ba54-47a08261c8e5

So here are some of the things that I do not understand:

1. How come the 2TB SSD is not listed in the fstab file?
2. I suppose that a command gets executed during startup to mount the drive, where can I see that command?
3. As mentioned above, when I inspect the drive in the disk utility...

The main screen shows the mount point as:

/media/erik/0d210810-0cf4-48f3-ba54-47a08261c8e5

And the "Edit Mount Options" screen shows the mount point as:

/mnt/0d210810-0cf4-48f3-ba54-47a08261c8e5

How come those two values are different?

4. My home directory is on the 256GB flash drive, how can I move it to the 2TB SSD?

5. How can I change the name of the directory at which the 2TB SSD is mounted?

Thanks in advance for any assistance.
