Can’t see the request destination

I am new with Wireshark and need help. I am trying to lookup POST requests sent from my PC app to my TV but when I send such via the PC in Wireshark I can see only the response from the TV. I checked and no filters are set. For example if the TV's IP is 192.168.1.100 and the PC's IP is 192.168.1.101 there are no packets that are with 192.168.1.100 as destination, all are 192.168.1.101 as destination, i.e. what's coming back to the PC as response. I can't see any POST or GET requests. Please help.
