Itr sent to ao 5 years ago!

my old ITR got transferred to AO 5 years ago.

No notice, no demand, no scrutiny, no email or SMS or letter, nothing, it is stuck there since 5 years.

I visited AO and he said everything ok but some system problem is there.

I have not asked for refund or anything but I want that state to change to "processed". I am getting worried, if they demand extra tax after many years I have to pay interest on all these years? Why can't they check my return sooner?
