Sandie,
When attempting to do begin the transfer, my Groups.io group name did
not appear in the drop down menu.
That usually indicates that you are logged into Groups.io using an email address which is not listed as an owner of that group.
While signed in, go to the group's pages and look at the Home button at the top of the list of nav buttons on the left. If you are logged in as a moderator or owner of the group there will be a badge showing your role.
The two billing screenshots could have been taken by someone who is a moderator of the group with the Billing permission. But that is not sufficient for initiating a transfer to the group.
