I think I should have explained at the beginning that I did not set up my Pihole. I hired an online Linux person to do it. He took over my screen and spent about a half hour entering in lots of terminal commands. I had no clue whatsoever what he was doing but at the end my Pihole was working and blocking domains. I have no clue how he set it up or how he configured it.
So it looks like I'll need to hire another Linux expert to fix this issue. Let me know if the issue can be easily fixed with a few simple commands. Although I don't think that's possible here.

So the question is why/how do you expect clients to use Pi-hole for DNS:
Do you run your Pi-hole on your router at 192.168.1.1?
Did you point your router to use Pi-hole as its upstream DNS server?
Did you point your laptop client to Pi-hole's IP for DNS?

Sorry but I'm totally unable to answer these questions. I'll hire someone to fix it. Thanks for your efforts to help.
