How To Use A React Page For a Github Domain Page - reactjs

Question

I seem to be having some trouble with Github. I would like to update the master branch, which is my old io_page, with a new io_page. My only problem now is that the page will not show the new_io page. I've tried using the build file several times (the new_io page is built in react) but the page doesn't work on the master branch. However, it previously worked on the gh-pages branch. I also set the homepage in the package.json to the domain name that I'm using.
My GitHub: https://github.com/Taniyah-L-Jackson/Taniyah-L-Jackson.github.io
What is currently showing: https://taniyah-l-jackson.github.io/
My package.json file:
{
"homepage": "https://taniyah-l-jackson.github.io/",
"name": "cra-io-page",
"version": "0.1.0",
"private": true,
"dependencies": {
"#testing-library/jest-dom": "^4.2.4",
"#testing-library/react": "^9.5.0",
"#testing-library/user-event": "^7.2.1",
"gh-pages": "^3.0.0",
"react": "^16.13.1",
"react-dom": "^16.13.1",
"react-router-dom": "^5.2.0",
"react-scripts": "3.4.1"
},
"scripts": {
"predeploy": "npm run build",
"deploy": "gh-pages -d build",
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {
"extends": "react-app"
},
"browserslist": {
"production": [
">0.2%",
"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}

Update: The page is working now. I had to change the scripts from
"deploy": "gh-pages -d build"
to
"deploy": "gh-pages -b master -d build",
and then re-deploy the build
