Format SSD and restore TM backup
Hold down the Command and R keys at startup to start the computer from the Recovery system. The Recovery menu that appears includes the option to restore from a Time Machine backup.

Second: Choose for Backup from TimeMachine.


And now we wait...

It would be wise to connect your machine using an network cable instead of WiFi.
