Help with domain connection

My custom domain derrickjohnston.ca is stuck on another project and I can’t find or access that project. I need it released and attached to my site getmortgaged.netlify.app instead.

When I try to add the domain to getmortgaged, I get “domain is being used by another project,” but I have no other projects in my account. DNS is already correct and confirmed on dnschecker: A record @75.2.60.5, and www CNAME → getmortgaged.netlify.app. Please release the domain from the orphaned project and let me add it to getmortgaged so SSL can provision
