Time machine cant see iCloud?

Time machine either doesn’t see the drive or
it’s seeing it but under a weird name and
my password doesn’t work. It says mycloud under
Network with an x and number but could be
Nearby user. Not sure what to do?

update:

seems to be working now all on one bundle. it took awhile but i let it sit last night in "prepare " and it not only backup up in full but also shows the older backups…so i guess it just needed time to reconfigure or something. thank you for the suggestions. I got lucky this time.

Follow this guide at “ Reconfigure Time Machine Backup”
