Hi Babychokatyler
welcome to the Apple (user-to-user) Community!
Re: "I can’t claim my artist account my old one id still on there"
" ... that was my old email, I cannot remember what was the login I use"
If you forgot your Apple ID email address or phone number (ie: your old Apple ID)
See if you're already signed in anywhere with that old Apple ID (eg: FaceTime, App Store, Messages etc.)
Check for any emails from Apple around that time ... ie: see the email address you used then.
or see: If you forgot your Apple ID - Apple Support
When you know your old Apple ID (usually an email address, though in some countries it may be a phone number.)
You may be able to rest your password:

Re: "I can send screenshots if needed"
We are all Apple users, like yourself, in the community, so, if needed, the screenshots would have to go to Apple.
(ie: No personal / private / data can be posted here.)

Re: "I really need my apple artist account"
Other online articles that may be helpful:
You may have given access to the artist page to someone else who would still know how to access it,
If you are the Admin you may have granted access to others (ie: they may still have access even if you don't.)
See how to manage access to your artist page:
https://artists.apple.com/support/1102-manage-access
Or, if you have recovered the Apple ID, and reset the password.
Try logging in with your Apple ID on this page
