TDS - Interest on Late payment

Use the same challan 281 to make payment online. This is very similar to payment of TDS. Once payment is made, add this challan on traces portal and appropriate the same towards interest.

So Instead of 200 it will be 400

Which Section should I Select?? The TDS payment I made  for Rent and Professional fees under Form 26Q

I should mention the amount in the interest head right??

Thank you for the response!

One More question what will be the due date for the interest payment??
