I want to verifying domain ownership for Netlify production domain (URGENT)

I am receiving the error “another site is using this domain” and would like to verify that I own a domain doelektra.lt (DOELEKTRA.LT not DOELEKTRA.IT, I mean it is .LT not .IT)
I want to use this domain on this website: doelektra.netlify.app
I already added a TXT record by instruction in your post
