How do I listen to my computer only?

Because I only want to detect all the connections that my computer is making on a specific app.

The easiest way is to create a capture filter for the mac-address of your computer. The syntax would be:

ether host 00:01:02:03:04:05

(assuming you are on an ethernet)

You can find your mac-address in each packet that your computer sends, so pick a packet that you know is from your computer and look into the Ethernet details.

Or try turning promiscuous mode off (by starting the capture with the "Options" item in the "Capture" menu and un-checking the "Capture in promiscuous" mode box in the Wireshark GUI, or by passing the "-p" option on the command line in the Wireshark command line, TShark, or dumpcap).

That also is an option. However, you will still see multicast and broadcast traffic from other systems, which might or might not be what you want.
