Please help me with restoring my Mac

[I Need a Drink]

I turned on iCloud Keychain two days ago and I was having some issues. I contacted Apple yesterday and they had me delete the Keychain, log out of iCloud and many other things and now my Mac is screwed and keeps saying there are problems logging into iCloud.

I want to just use my Time Machine backup and restore to a backup from before I turned on the iCloud Keychain and all the changes that Apple had me do yesterday. Is this possible and how would I do it?

Thanks

Yes.... command-r boot to recovery. Then use Disk Utility to erase Macintosh HD to Mac OS Extended (Journaled) format. Then attach your TM disk and click "restore". Follow the prompts and you will get to a screen that looks similar to this. Scroll down to the date you want to restore from then select that date and continue. This will restore the entire system to that old date.
