I think you are right - I changed each GDAX deposit to "[In] Income" and the warnings are now GONE.  Now I just need to figure out how to reconcile this mess with the 1099K I received from GDAX.  I know I have to to fill  out Form 8949 (Sales and Other Dispositions of Capital Assets) with the information provided by cointracking.info, and that will go on my Schedule D.  But where do I reconcile the 1099K?  Will that go on a Schedule C?
