While registering with the e-filing site - it has asked either to give the TAN No. if any TDS is deducted OR give the details of challan paid.
As there was no TDS deduction , I paid challan on 27/11/2012 for Rs. 500.
This reeceipt of this is is confirmed by tin-nsdl.com site with the details of 'CIN'.(tin-nsdl.com)
Now when I try to register with this details..........
