Remember, this is from black’s perspective, so the board is flipped. Also remember that you need to indicate which piece is moving (in this case, the knight). This notation means that a pawn has moved to e5. Ne5 is the correct way to notate this move. In this case, the knight took the pawn on e5, so another way to notate this would be Nxe5 where “x” means it takes/captures.
