One of my partitions doesn't mount

Question

just upgraded to 18.04 and installed alongside win10, I followed a guide to do so. I must admit when it said where to mount the partition used for storage I was dubious, but did it anyway.

It said to mount it /home/storage. It appears when I use lsblk, but I can't figure out how to mount it.

Here is my lsblk output, the drive in question is sda.
