Hi, @Irene Peterson
Do you mean your Desktop computer is missing from the "Devices" section of your Microsoft account, or that Microsoft 365 on the Desktop is not showing as activated?
If Microsoft 365 is already installed on the Desktop, open Word or Excel, then go to "File" > "Account" and check which Microsoft account is signed in. It should be the same account that owns your Microsoft 365 subscription.
If the Desktop is not signed in with that account, sign out of Office and sign back in using the Microsoft account that has the subscription.
If the issue still persists, please let me know exactly where the Desktop is not showing in your account.

Thanks!
