Tds challan corrections

My friend has filed his tds return for the Ist Quater 2011 for his company one month after the due date with all the details and stuff.

But the problem is while filing the challan online his has made quite a few mistakes: entered wrong A.Y. in few challans and the interest is shown as surcharge for employee TDS. So far no query has been received from the Assessing Officer, but he is willing to write a letter to the concerned TDS Officer for corrections.

My question is should he wait for the query from the TDS department or write a letter from his side explaining the corrections. How much time it will take for the corrections and will it affect the TDS return for the 2nd Quater 2011.

Thanks in advance.
