You have two life insurance companies coverage one is 20000 the other is 10000 how much is my total coverage?

If they are both term life insurance policies, your total coverage would be $30,000. If one, or both are permanent life insurance policies, there may be cash value inside the policies that adds to the payout from the life insurance policies, so there may actually be more than $30,000, if you include the cash value inside the policies.
