I am trying to add a txt record in my Domain : sjpanel.com to verify for Google Webmaster.
Even when I add the property in the DNS it is showing a hidden TXT record for sjpanel.com
ca3-0ece9d714db94cdd9b91cc2b09cb7354
I want to remove this record or maybe add my verification code before this so that I can verify my site at Google.
I looked up for this issue and found that this default TXT record is used by Cloudflare for internal usage.
You can have multiple TXT records at the root of your domain, that one is just used for CF to issue a SSL certificate.
Have you tried entering your verification TXT record already? If so, take a screenshot of the DNS dashboard and post it here and/or post your domain so we can look into it.
