If you have filed online return by mentioning only the tax paid by you and not BSR code and challan number then you can file online rectification u/s 154. In any case after your return is processed by CPC you will receive intimation u/s 143(1) in which demand will be raised as payment made by you will not be verified in the absence of BSR code and challan number. In case return is filed manually you can file rectification application to the AO mentioning the challan number and BSR code and a copy of challan if required may also be furnished.
