The B and W Companion hitch for GM fifth wheel rail kits part # BWRVK3770 requires the GM factory fifth wheel rail kit installed in your 2019 GMC Sierra 2500. The only place you'll be able to get the correct rail kit is if you went to a GM dealer.
That said I can help you install a different B and W Companion slider hitch # BWRVK3400 in the bed of your truck with the B and W Turnoverball rail kit part # BWGNRK1016. This is a great solution for trucks like yours that don't have the factory rail kit which also doubles as a way to tow a gooseneck hitch too.
I attached an install video for this rail kit in a similar truck as yours for you to check out as well.
