I have never read a definitive statement about exactly when you need to have your KTN in your reservation but I believe you need to have your KTN in your reservation earlier than 2 or 3 hours for PreCheck. I have always assumed something like 24 or 48 hours in advance. You may want to post in the Trusted Traveler forum for a better answer.
When I made my most recent TK reservation I never saw anywhere to enter the KTN. I just checked it and all I saw was an APIS page for entering passport and visa information.
Below is pasted from the TK website. The bolding is mine:
