I looked at the domains on your account and I see the one that needs verification but I do not see the TXT record on it, only what looks like an extra CNAME mislabeled as a TXT
dig +short TXT www.example.com
cname.vercel-dns.com.
In the domain settings for your project, you should see a “Fix” button that opens a dialog like this. You need to copy that TXT record (Name and Value) and enter it in your domain registrar’s settings (Namecheap, GoDaddy, etc)
Once that’s done and it’s propagated (which in 2025 is usually within a few minutes but occasionally does take a day) then that same dig command should return your vc-domain-verify TXT record
