First of all, the coloring on your turtles head is beautiful. I've not seen that much red outside of the "ears". Mine has a hint of a red stripe, but nothing like yours.
That groove you are seeing is layers of scutes that aren't shedding. The most likely issue is basking. How often does your turtle bask? What is the uvb source, and how old is the light?
