Income tax returns

my wife used to file income tax returns till 2010 but later she had no income except the interest on fd n that too in the exemption limit so our CA said she doesn't need to file returns n thus we stopped filing returns but now for assessment year 2012-13 and 2013-14 we got notice saying that we haven't filed returns n code is CIB-403 saying time deposit exceeding rs. 2,00,000/- with a banking company and TDS-194A saying TDS return-other interest (Section 194A). what is the meaning and what we need to do now. when I checked online under compliance nothing is showing there. please advise.
