Itr related query

I have filed ITR 1online, however yet not sent the ITR V to CPC, Banglore.

On reviewing my ITR 1, I have noticed that I have forgotten to claim exemption towards "conveyance expenditure" in the e-return filed by me.

Now, what course of action should I opt for

First : To send the ITR V to CPC Bangalore & after confirmation of receipt of ITR V by Income Tax deptt, file a Revised Return claiming the exemption left out by me.

Second: To upload the corrected ITR utility at incometaxindiaefiling.gov.in before sending the signed copy of ITR V 

Thanks for your support...
