Tds against flat purchase

Dear sir, I have purchased a flat in navi mumbai last year in march 2015 in joint ownershiip with my wife. cost of the property being more than 50 lac, i have deducted 1% TDS and filed Form 26QB last year. last week my wife received mail from tdscpc that she has purchased a property and not filed form 26QB and form 16B. so my query is whether my wife should also furnish the same separately or not. as i have already furnished aall the details on time.
