You should have shown the details in your Income Tax Return for that financial year. Since you have omitted doing so, it is preferable to wait for any communication from the side of Income Tax if any, then you explain it to them that you were unaware of the law and hence missed out in declaring the details. Though you have not evaded any taxes.
Trust this clarifies your query.
