Trouble adding users

I installed everything last week and the automatic config worked fine.  Today, I did a Time Machine restore from an iMac to one of my MacBooks and tried to use Jump Desktop.  I can see the PC I have just fine and was seeing the MacBook I was on (as the one deleted to make this one).  So I deleted that one.

How do I add the other Mac (the iMac) as a connection to this one?  Do I need to completely delete everything and start over?  Seems extreme.  

Anyone who can help me here would be most appreciated.
