My saved games aren't labeled in such a way that I am able to know which one you would need for this. The note only appears after you have done certain things, but no way for me to know what you have completed.
The game is nonlinear and there is no way that you can get stuck by doing things in the "wrong" order, so if the note has not appeared when the walkthrough says it has, ignore it and carry on with the game. It just means there are other things you need to do first. You will see the note when the time is right, depending upon what you have done.
