You can check the archivement list, and see which tlsq you missed. In my experience, all tlsqs will trigger when you slow down. I stopped rushing when I was in year 5 chapter 1 because i missed around 20 tlsqs. Almost a month after that, I'm only in year 5 chapter 6 now but all my TLSQs and quidditch side quest were shown up. I just finished festival fun today. I hope The second quidditch cup will trigger after 24h because all my TLSQs are up to date
