Hello Ranjith Kumar!!
Actually, if you have payed the amount for TNEA, it would reflect within 4 hours of payment.
But, you are stating that it has become a day. You can call to the TFC and clarify the payment details such as 'whether it is payed or not?', or 'whether you want to pay the amount again?'.
The list of TFCs and the contact details are given in the official website of TNEA.
BEST OF LUCK!!
