Minecraft is port forwarded properly but can’t log in

Two things:

• first you have two conflicting rules in your port forwarding rules, you are telling to forward port 25565 either to 192.168.0.1 either to your machine 192.168.0.104, you need just the latter one
• if your brother computer is inside the same network of your laptop then you don't need to open any port on the router (unless you want to allow people from outside to connect to the server) and you have to specify your local IP address (192.168.1.104) when trying to connect.

Of course any client from outside your network should try to connect to your external IP (the one shown in the port checker page).

It looks like you have your public IP typed into the Private IP field on your port forwarding setup. The public IP is assigned to your modem/router by your ISP.

You will want to instead put your private/internal IP in that field. This is the IP assigned to your computer by your router. You can find your internal IP (under Windows) by opening cmd.exe and typing ipconfig. You will look for a line that says:
IPv4 Address.....: 192.168.x.x

Type this whole address into your router's port forwarding configuration as your "Private IP". As Kevin points out in the comments, if the computer you are using as your minecraft server is different from the computer you intend to use to play, this applies to the server computer.

This tells your router that when it is accessed on port 25565, it will forward the information to a specific computer on your network, specifically the one you list in that box. Your friends (outside your network) will still use that public IP to contact you.
