The packet knows to go to 24.89.12.11, because that is what your IP address will appear as to the computer sending the packet.
But it does not contain the information to go to 192.168.1.4 after it reaches 24.89.12.11
192.168.1.anything will be seen to the outside world as 24.89.12.11, and the sender computer will send it to 24.89.12.11, because it has no knowledge of the structure of the internal network. Even if it did send it to 192.168.1.4, that would go nowhere, or it would go to the wrong computer, because that IP address is only used inside your network for your computer.
You are right in that the TCP\IP protocol has the information to send the packet to the right computer, but it only holds one IP address, not two. And that IP would be 24.89.12.11
