Hello.

NTA is providing students the chance to correct their Jee mains application from 11 to 15 March. You can make changes and corrections in your application form during this period. You cannot change your exam city. You will have to pay a fee if you are changing your category from a reserved one to general category. Also, you will have to pay a fee if you want to attempt both paper 1 and 2 but haven't mentioned it in the application earlier. No refund of fee will be given if you're changing your category from general to reserved or deciding to drop any one of the papers.

Hope this helps
