Cannot upload WP and site built on comp to cpanel

Help me please.

I built a WP site locally on my computer and I am now trying to upload it to my website using either cpanel or FTP (filezilla). FileZilla is not letting me login properly and cpanel is breaking my heart. I have been attempting to drag and drop every single wordpress file from my computer to cpanel, and I think I have most of them up there, but I do not even know where they are or what to do with them.

I have no experience with taking a locally built site and uploading it to a remote server and I so desperately need to be able to do this.

Somebody help me, please.
