JEE Main is being conducted twice by NTA for the first time so it is difficult to predict and NTA Scores for both of the attempts will be taken into consideration and the best of the two attempts will be considered for ranking purposes.

As per the previous year, The closing rank of home state quota for CSE branch was around 14436 as General category of NIT Jamshedpur. You can check the cutoff for other branches with the given below link.
