I'm locked out of my Coinbase account, and Coinbase is no help and there's no way to reach a real person to talk to, how do I file my taxes without access to my account?

I can't reset my password "I never receive an email when I try to" and when I call they say they don't recognize my number and it's not associated with any account, I will take legal action against them but for now I need to know how to do my taxes with access to my crypto account?
