Ok the dish coax needs to go to the single post on top of the splitter and the "Power to SWM" goes to the red port and looks like that is where you have it. Remove the coax from the "To IRD" and terminate it with the cap that should have been there.
The DECA BB should be connected by an Ethernet cable to your router to provide the internet to the SWM system and that "to dish" coax should connect to another splitters red port to provide the signal to the Genie.
Do you have wired or wired or wireless minis?
