Interest on tds

As the I.T. Deptt. is sending notices to all persons who have make default in payment of TDS and the demand raised by deptt. for interest is cumulative of all sections e.g. 194C, J, H.
So my query is that while depositing the same one should calculate interest for each section separately
or
deposit the all interest under one challan.
& if the second option is correct then how to fill the challan 281 (because it asks for the specific section) and to enter them while revising the respective return.
