Can't access Desktop via Ubuntu

I am brand new to using the command line so bear with me. I am not able to access my Desktop from my root directory. The furthest I can get is /home/sam and then there isn't anything from here. I have tried /home/SAM/Desktop and starting from /. The only way I can access folders is using /mnt/c/Users/Sam/Documents/. However, I believe this is storing items in a mounted drive, which is causing my endless problems when trying to run repositories via VS Code. Any help is appreciated!
