Rectification under section 154

Dear Friends,

I have received an Intimation from IncomeTax regarding invalid TAN of deductor due to which we cannot claim credit of the amount .Further, it is written that we have to make an online application under section 154.Kindly correct me if i am wrong:

1. We have to file revised return ITR -6 (company) (one in the excel) after making changes(ie. writing the correct TAN) and convert into xml once again

2. Log in then Home - Rectification - upload the xml file.

Is this the correct process? or there is some other process ??

Thanks in advance.
