Body does not change form box mode to smooth mode
Can you share a public link of the design?
You could also share a local archive.
The STEP file will note containt the T-Splines information necessary to evaluate the issue. ... Unless I'm misunderstanding the issue.. :-S

The current file has a lot of problems as you've probably noted from the Repair Body command. If you delete everything that's not a 4-sided face, you can get the model to become smooth again. See below design for reference
Ideally, only four edges should meet at each vertex. Having a greater number of edges meet at a vertex is okay, but makes it more difficult to keep the surface smooth. Line segments should generate rectangular regions with 4 sides (as much as possible). Regions of 3, 5, or more sides (n-sided regions) will be subdivided and make it difficult to control the smoothness.
However, I think it may be easier to start over from step 1. Check out the below design:
...and screencast:
The screencast is admittedly too long, but it shows how you might be able to get started. It was my first go, so sorry for the unpolished viewing experience.
I hope this helps, either way.

I am not entirely sure why you would even use T-Splines to create that geometry.
If you need to create sharp edged geometry, then surface modeling is a better option.
That being said, your geometry violates some basic T-Spline modeling guidelines. The two faces highlighted in blue are n-cons with more than 5 vertices/edges. While that sometimes works, in this case you have also creased almost every edge.
That inherently leads to conversion problems!

The geometry is poorly constructed.
I recommend that you start over from scratch and Attach your file here after each and every sketch/feature for guidance. Your Sketch1 (and many others) is not fully defined and I suspect if I ask some questions about the sketch you will agree with me the geometry in the sketch is not what your really want.
Are you attempting to reverse engineer an existing part from the real world?
If yes, can you attach an image of the original (or something similar)?
Why are these contiguous faces?
Wouldn't this be easier as one Extrude, Fillet and then Shell?
Where (in space if I take this to Inspection) are these circles?
Why duplicate sketch geometry?
Is this really the intended distance between centers?
Edit: As you start over from scratch using what was learned from this attempt - I recommend that you start a new discussion thread with a link back to this thread as reference.
