When you're granted a boost (or other item) it shows up in your notification page. The default is "K" I believe to open this page. There you'll see pending notifications (squad invites, friend requests, etc.) and you should see a boost that if you accept it will go into the store of boosts the character you have logged in at that time. So while the notification will show up on all characters you log in on that account be sure to only claim it on the character you would like to use the boost.
