Is a Roth IRA early distribution not taxable if I am 58 years old, permanently disabled and I have had the Roth IRA since 2003?

Is a Roth IRA early distribution not taxable at all if I am 58 years old, permanently disabled and I have had the Roth IRA since 2003?

 If so, what do I need to prove that I am disabled and the amount I am taking for a distribution – $30,000 is part of
contributions and not earnings? I want to take this withdrawal for year 2019 and I am concerned about the taxes
