Issue when adding a domain to Netlify that was previously used with another Netlify account or team

Please help to check the issue when I added my own domain into Netlify. The error message showed:
thenexova.com or one of its subdomains is already managed by Netlify DNS on another team.

I already added TXT record to DNS configuration on my own domain. Please help me to check and fix it.
Thank you very much.

I’ve done with the DNS configuration

I’ve sent this request to our helpdesk, we’ll follow up via email.
