To display your Library folder in your user home folder,
- In Finder, go to your user’s home folder (usually similar to your username on the computer), then while you have that open in Finder,
- go to the View menu in your menu bar,
- click on Show View Options, then
- in the new window that comes up, check the box next to Show Library Folder
That should make your Library folder visible among the other folders inside your user home folder.
