virtual machine doesn't use allocated disk space

I am running manjaro in an Oracle VirtualBox to test a virgin install of a set of softwares. I am getting an error that there is no more disk space on a particular download, however, when I set up the vm in the VirtualBox Manager, I am allocating it plenty of space (> 100GB). I have tried changing this from dynamic allocation to a fixed partition, but this did not solve the issue. When I run lsblk, this is the output:

NAME  MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
loop0   7:0    0 130.6M  1 loop /run/miso/sfs/livefs
loop1   7:1    0 581.9M  1 loop /run/miso/sfs/mhwdfs
loop2   7:2    0   1.5G  1 loop /run/miso/sfs/desktopfs
loop3   7:3    0 702.8M  1 loop /run/miso/sfs/rootfs
sda     8:0    0   134G  0 disk 
sr0    11:0    1   2.9G  0 rom  /run/miso/bootmnt

So to me it looks like the 134gb partition needs to be mounted? I run sudo fdisk -l to see where it is:

I am running the installs from my $HOME directory (which in this case is /home/manjaro), so I try sudo mount /dev/sda /home/manjaro, and this is the output:

mount: /home/manjaro: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error.
