Hello Aspirant,
It seems you are little bit late because NIT Srinagar or any other NIT take admission for their B.Tech courses only through JOSAA or CSAB counselling using your JEE-Main score and now JOSAA counselling has already been completed and CSAB counselling is also about to complete within few days.
So now you have to wait for next year and in next session 2022-23 you will have to again appear for JEE-Main 2022 and then only you can sit in the JOSAA or CSAB counselling.
You can check out complete details about JOSAA as well as CSAB counselling from the link given below :-
