Issue with Publishing NPM Package (org.couchdb.user:USERNAME' is not in the npm registry)

Issue:

I'm trying to publish my npm package https://www.npmjs.com/package/react-native-ultimate-modal-picker and it's coming up with the error. It's been 9 months since I last have made a publish and I just updated a ton of code and files. I also set the publishing from NPM to GitHub, but I think I reverted those changes?

Question:

1. Why am I getting the errors below?
2. How can I make sure that the npm package is published to https://www.npmjs.com/package/react-native-ultimate-modal-picker?

Errors:

org.couchdb.user:jefelewis' is not in the npm registry.

This package name is not valid, because 
npm ERR! 404  1. name can only contain URL-friendly characters

npm ERR! code ENEEDAUTH
npm ERR! need auth This command requires you to be logged in.
npm ERR! need auth You need to authorize this machine using `npm adduser`

Process:

1. npm login
2. Enter login info (Username: jefelewis)
3. org.couchdb.user:jefelewis is not in the npm registry.
4. The issue is that my username is jefelewis (https://www.npmjs.com/~jefelewis)
