It's a very common questions, you should use the search before posting, and avoid waiting for someone to reply...

In most cases, you will have to "takeover" the tenant, follow the steps here: https://docs.microsoft.com/en-us/microsoft-365/admin/misc/become-the-admin?view=o365-worldwide

If that doesn't help, go over the suggestions here: https://techcommunity.microsoft.com/t5/microsoft-teams/quot-someone-has-already-set-up-teams-for-you...
