State tax filing

My income is over the threshold for both NJ and NC, but in both states I only have income from my job (no investing). As far as credits/any other items, I do not have any out of pocket schooling expenses. What is the difference between the CD and the Free edition? Does the CD give me access to the CPA feedback vs. no feedback on turbotax free? I am pretty confident with my ability, but don't mind paying a little bit extra to ensure everything is done correctly.
