Hey there

Hope you are doing well and keeping fit...

So heres your answer to your query...

Since you have submitted your application fees right now then you have to adhere to the deadline which they have mentioned in the rules and regulations list and submit it immediately as they have mentioned accordingly. Or else your application details might be made invalid and henceforth leading to its cancellation. So please try to submit it within the scripulated time as they have mentioned.

All the best for your future...

No you should submit it by tomorrow (the mentioned last date), and if you fail to submit it by time then your application may be rejected though you have paid your application fees, as they might consider as you have got some other institution to apply. Better try contacting the authority where you have applied and explain the issue.
