Hello Aspirant,
No it won't be returned to you, instead you should get another print of your Admit card for JEE-Main and application form is not required so get another print of an admit card of JEE-Main and that you can carry it to the examination center but note that this admit card will also be collected from you by the invigilator. So always keep a soft copy of it in your PC/Phone for future reference.
As per the guidelines for examination day of JEE:-
>>>> You should carry your Admit card along with one government ID proof.
>>>> Masks are compulsory in the wake of pandemic.
>>>> There you will have to maintain the distance of at least 6 feet.
>>>> When you will enter in the examination hall you will have to give your left hand thumb impression on attendance sheet.

I hope you got it.
All The Best for your Examination :))
