Capital gain tax

sir

i sold my property for 29 lakh in Jan 14 and purchased new property for 65 lakhs in April 2015. i filed ITR1  for AY 2014-15.  i did not mentioned the LTC gain tax. i paid 65 thousands TDS on the behalf of seller in April 2015. now whether i need to file ITR 1 or 2 , do i need to mention the purchase of property. do i need to change the ITR for AY 2014-15.

thanks
