Hello,

You can't apply for NEET as you already completed the year for intermediate. the students who are in 12 and the results are awaited can apply for neet.

You have completed your 12 in 2019 and yet your one paper is still back so it won't get considered. so First clear the paper and prepare for NEET meanwhile and then apply for it and appear the exam.

The minimum percentage considered is 50% in PCB and your Biology subject marks are not there then you are satisfying the eligibility criteria.

Hope it helps!
