The home state quota of JEE Main is that state from where you have completed your class XIIth. Since you'll be completing your class XIIth exams from Haryana, thus the home state quota that you will be able to avail will be of Haryana.

Since you will have home state quota of Haryana, thus you will find it easier to take admission in various courses of NIT Kurukshetra, which will provide you admission at a lower rank than usual due to your HS quota.

Hope I have answered your question. All the best!
