I answered you in the Lightroom Beginner forum. But just in case you missed it:
The profiles are never listed by camera model. You see Adobe Standard, and that is the Adobe standard profile for your camera. That is the only profile Adobe provides for your camera. Adobe produces camera-matching profiles for Canon and Nikon cameras primarily. But for most of the other cameras Adobe only produces the one standard profile.
