I have chose wrong gender in the JEE Main application form and i didn't see it until now

I am 17 and male, have misclicked my gender as female while applying for jee mains and i didnt notice it until now and i have already finished my first session. they didn’t notice it there in the exam center and I didnt either. i don’t know how much of an issue this is because i have paid 1600 as registration fee while its 1800 for male, which is borderline fraud. only on feb 10, after the answer key came out i saw that i have misclicked the gender. is there anyway to right this wrong and how do i contact the NTA about this?
