Thanks for the A2A.
If you got the same seat of Round 1 during JoSAA 2020 Round 2 counselling and if you had submitted Float as your willingness, then you need not do anything to participate in subsequent rounds with your Float option. Unless you change your willingness, Float option will remain till the last round. If a new seat is allotted in subsequent round, you can opt to Freeze/Slide/Float as per your wish.
