Could you please take pictures of each box with the switches pulled out so we can see the wires in each box? The important switches in a 3+ way switch are the 3 way switches, ones with 3 wires. The 4 ways can be ignored. On the 3 way switches one screw terminal will be a different color, usually black or bronze, called “common” and that is the one to pay attention to. On one 3 way the common will be your line from breaker and the other will be load to your lights/fixture.
