Actually it is about your local git, and the the default remote name is 'origin'
In the vscode terminal/console type this command:
git remote set-url origin new.git.url/here
so, it will update your repo address.
if you want to add a new one, instead of overwriting the old one
you can simply type this commands:
git remote add myorigin git@github.com:User/UserRepo.git
then when you want to push/pull/fetch you should do like this:
git push -u myorigin master
myorigin is a custom name or alias for your new repo address.
you can call it whatever you like to.
Also, you can check existing remotes with:
git remote -v
