I think one of the problems with MAs in CW is that they focus very much on generalised inspiration and line level analysis, when novels require a much bigger over view.
Teasing out a plot that works on a macro level is one of the main skills a writer needs ( obviously) yet remains tricky for many. So you're not alone in this 
.
My advice would be to try to forget the line level aspect of writing for now. Beautiful descriptions, snappy dialogue, voice; that can all wait.
What you need to focus on is story. What happens and perhaps more importantly to who.
Think of your favourite books and films and box sets. Ask yourself what was it about the MCs that drew you in. What happened to them and what did they do.
It might help to analyse these stories next to some classic texts on plot; The Hero's Journey, Story, The Seven Basic Plots.
Some writers are sniffy about this, feeling that analysing story like this results in formulaic work. But I think that entirely misses the point. Great cooks don't ignore the recipes of David or Roux, do they?
Once you can see how story works you can then set to making your own. Why not apply the Hero's Journey ( mostly I use the Heroine's Journey) to your MC and note down what might happen to them at each stage. Use broad brush strokes initially, then get more and more detailed. Remember you're not show horning your characters into set pieces, you're simply placing them at a plot point and asking how they would authentically react.
Eventually, you should end up with a coherent plot.
