I need to start my taxes over from Mario montemayor it is a suspender the biggest mess up I've ever seen and my girlfriend tried to help me and you guys put her on a tax return of mine as the ID numbe

If you have not filed your return, paid or registered, you can use this link to clear and start over:

If you are unable to clear and have not filed yet, you can just abandon your account and start over in a new account. 

Trusting somebody else to do your taxes for you -- sometimes it works, and sometimes it doesn't.

If you were trying to use the same account that your GF already used that is most likely your issue ... accounts cannot be shared.   Start again in a new account of your own.
