Answer: L.
The idea
Work in positions, not letters: subtract for 'to the left' and add for 'to the right'. Convert back only at the end.
Shortcut. Use the EJOTY anchors (E 5, J 10, O 15, T 20, Y 25): T is 20, eight to the left is 12, and two after J (10) is L.
Common trap. "M" — counting T itself as the first of the eight steps (T, S, R, Q, P, O, N, M); the count starts at S, so it lands on L.
