Why
The 2♠ is a blank that changes nothing: the Q-high board still favors BB's checking range only modestly and neither player is uncapped, so equities stay flat. Your A♥J♥ is just ace-high with no pair and no real draw (a King-Ten runner is your only straight, and the lone backdoor spade is dead), so you have showdown value but nothing to bet for. In position with the action checked to you, checking back captures pot control and lets your ace-high win at showdown unimproved rather than turning it into a bluff that folds out worse and gets called by better.
Key idea
On a blank turn in position, ace-high with no draw checks back for pot control and showdown rather than bluffing.
Common mistake
Turning a hand with clear showdown value into a bluff-bet, which only folds out worse hands and gets called by everything that beats you.
