Hi @wade chapman
Thank you for posting question to Microsoft Q&A.
As this is forum and I am forum moderator, I am not able to access to Microsoft internal data to help you with this. With your request to remove the domain from inaccessible tenant, you will need to raise the ticket as Global Administrator in Microsoft 365 Admin Center (https://admin.microsoft.com)
By doing this, you will reach out to Microsoft 365 Support Team (instead of Forum moderators - only in this Microsoft Q&A) and they could help you to transfer this to Data Protection team - which could assist you in removing the domain from your inaccessible tenant. This process might take some time but assuming that you provide proof of ownership to them - you will eventually regain the domain and add it to your new tenant.
Please help me to raise this ticket and provide me the update if possible. I really hope that you will regain the access to that domain as soon as possible.
