Push keeps pushing wrong files

I’m sure this is such as noob question but we pushed a new repo and it went fine when we created it but now we have a new branch and code that was started over. We want to push that to a new branch but when I run git add -A, then git push https://<GITHUB_ACCESS_TOKEN>@github.com/<GITHUB_USERNAME>/<REPOSITORY_NAME>.git, it is pushing to a new branch called master and it is pushing files from another repo we cloned the original files from. Any help would be great.
