Looking at your data my fist guess is that the Edge1FCID and Edge2FCID values are not correct (in the test1 Turn Feature Class). These should be "Feature Class ID" (not ObjectID). You probably only have 1 FCID value (1 per line feature class).
I suggest getting to know the Turn Feature Class data model by observing some example edits and letting ArcMap populate the correct IDs for you. In other words, make your Network Dataset from the line features first. Build it. Now add a new Turn Feature Class using ArcCatalog (or GP). Then add the Network Dataset and Turn Feature Class to ArcMap, Start Editing, and digitize a few turn features. Looking at the FCIC and FID values automatically populated will help yuo understand how to construct it correctly yourself.
Then if you are still having trouble, perhaps show us a picture of a turn with the FID (feature ID) values labeled on the line features and what the turn feature class field values are. This will allow us all to just look at your turn features without understanding your original data model.
Also, what format are these original turns specified in? If they are from an ArcView 3.x or ArcInfo Turn Table then there are GP tools to migrate them.
