Hi

You will have to first check whether you belong to OBC category or not in the centre list.

You can check it here - http://www.ncbc.nic.in/user_panel/GazetteResolution.aspx?Value=mPICjsL1aLvAXpHv5rPBH9SN4In7SbbD7oTvOlvDet%2fYFgcvB5tucZnCxSsGqvwE

Select your state and then check it.

Also, you will have to produce your OBC category certificate at the time of admissions.

Know the complete JEE main eligibility here - https://engineering.careers360.com/articles/jee-main-eligibility-criteria

There is general, OBC-NCL, SC and ST categories in JEE Main

To apply for reserved category you have to produce original certificate issued by the competent authority which is applicable centrally at the time of Seat Allocation Process as well as at the time of admission.

State list category students who are not in central list must choose General category.

Good luck!!
