Headlights and high beams working no flashers, signals or tail lights

2018 Toyota tundra . I tow a trailer occasional , last time unplugged the trailer in it was doing some weird things , now my tail lights , brake lights turn signals and flasher aren’t working but head lights and high beams are fine , I’ve checked fuses but maybe I’m not checking the right ones . Any help would be appreciated . I’m at a loss
