Musician profile

hi, how are you? I wanted to reach out regarding my music on Apple Music and iTunes. I’m a singer/songwriter that uploads music through distro kid. Then distro kid distributes my music to you guys. A friend pointed out to me recently that my old artist name is on iTunes/Apple Music and for Spotify my current artist name sits. Which means all the current music I’ve made is on two different profiles. So nobody can find me. I have my old debt card on all accounts and proof that it’s me but I want switch everything over to my current brand. How do I do so?
