Name is already taken, {domain} is conflicting the ownership with other existing zones even after deleting it from previous account

Hi from different account domain name is deleted but still showing me same error .
How to resolve this issue ?

Hey @algoalliance

When you remove the domain from the other account, did you remove it firstly as a custom domain for the Netlify site, as well as remove it from the Domains section of the Netlify UI?

Actually i dont have another account from where it is removed i asked person to do it he said he has deleted it and deleted project also. i know only that much. i have added txt record also

What is the domain this is regarding?

it is landing page domain name :

Hey there, @algoalliance :wave:

Thanks for reaching out about this. Could you please try setting the txt record again? I am unable to see it on my end still.
