Income Tax 26AS

Dear Learned Members

I am retired employee and my wife is housewife, I get pension on monthly basis.

Last year we have sold our old house and brought a new flat.

Since the builder wanted a co-owner to be registered, while registering new flat, they added my wife's name.

Now when I see 26AS, the same amount of sale and purchase is mentioned in both of our 26AS (me and wife), where as the transaction was done only once.

Please advise if both of us have to file separate returns for same transaction.

Thanks
