How to do texhash on texlive 2020 installed on Ubuntu 2018 LTS so VS code can recognize personal style files?

I’ve recently installed TexLive 2020 on my Ubuntu 18.04 LTS machine. I’ve completed all instructions mentioned here. I’ve created a couple of personal .sty files where I put in the directory /usr/local/texlive/texmf-local/tex/latex/local/. When I do texhash I receive the following message.

when I do sudo texhash, I get

Typing which texhash results in /usr/local/texlive/2020/bin/x86_64-linux/texhash.
Please let me know if there is anyway that I can use my own .sty to compile my .tex files in VS code.
