How do you convert the .STEP file to another format that I could import? Or is there a series of steps to get to this process?

I would really appreciate your help. Thank you.

I stumbled on this problem some time ago, and had a hard time finding a converter not costing an arm... Here is the process I use:
- Download and install FreeCAD https://www.freecadweb.org/
- Open your STEP file in FreeCAD
- Switch FreeCAD to mesh design mode
- Meshes -> Create mesh from shape (option: standard meshing)
- Select the meshed result, then meshes -> export mesh -> ASCII STL (*.stl)
- Convert the resulting stl to LDraw file using stl2dat (https://sourceforge.net/projects/stl2dat/)

stl2dat is also included in LETGUI distribution that has the benefit of providing a GUI around command line tools (http://ldraw.heidemann.org/index.php?page=letgui)

Feel free to ask if you need more details!
