Abaqus - Need Help placing loads on my baseplate element

Hello everyone, I am new to Abaqus and I am doing a project for my Finite Element analysis class. I am working on a monopole baseplate that I have modeled in ABAQUS. I have the geometry and everything right, it is a circular baseplate with a cutout in the middle for the monopole tower itself. The problem I am having is I am trying to input the reaction loads where the bolt holes in the baseplate would be but I am not quite sure how to do it. I placed reference points at the exact x-y coordinates where the bolt holes are located, and they are not tied to the element itself. In the monitor section of the job it tells me I need to create a node set but I cannot seem to find anywhere to do it. Please help! Attached are pictures and the file that I am working on. Thank you in advance to anyone who reached out. I am trying to do a linear, and nonlinear analysis on the plate. And the only thing left for me to do is figure out a way to attach the loads so that they are acting on the plate at the exact points that I have referenced.
