Subdomain already managed by another team

Hello Netlify Team,

I deleted my previous account because I was not able to remove cache from the previous website. When I started to upload new files, all the old photos transferred to the new website. Due to this issue, I decided to delete my account and create a new one from scratch. However, when I tried to add my domain “swendl.com,” I received this message:

" swendl.com or one of its subdomains is already managed by Netlify DNS on another team."

I have already created a TXT record for the domain.

Please help me resolve this issue. Additionally, I would like to know how to delete all websites along with their caches in the future.

Thank you for your assistance.
