Should rectify return or revise return

You should revise the return under section 139(5) of IT act 1961 and you need to state the reason of such changes which may be necessary for the AO to compute your income from the revise return. 

Sir, i had done a mistake at the time of filling the return i.e i had claimed TDS of two parties in the name of single deductor due to similarity of name, now income tax department has disallow the TDS of a party out of two, whose TAN no. is not matched.

Now my query is, should i go for rectification, if yes then what is procedue to rectify the reurn.

THANKS IN ADVANCE. PLEASE REPLY
