Facing difficulty!!

DEAR FRIENDS AND EXPERTS,

I HAVE BEEN TRYING TO FILE A RETURN FOR AY 2011-12.
THERE IS NO JAVA UTILITY AVAILABLE FOR THAT BELATED RETURN AS ON THAT DATE. BUT EXCEL UTILITY IS STILL AVAILABLE.

AS I WAS FILLING UP THE RETURN FOR AY 2011-12 AND SELECTED THE OPTION FOR RETURN UNDER SEC 139(4), AFTER CLICKING ON "CALCULATE TAX" BUTTON , THE POP-UP SHOWS AS FOLLOWS :-

"RETURN FILED DATE IN SHEET: INCOME DETAILS IS ONLY REQUIRED FOR REVISED RETURNS"

I am unable to understand what it is supposed to mean as I am not being able to generate the return and also interest penalty is not being calculated. I have a huge TDS waiting to be adjusted for that year. PLease suggest what am I supposed to do!!

THANKS
