Notice u/s 143(2) for detailed assessment

This is your first notice. At this moment, just submit a computation of Income. AO will share a detailed questionnaire later. 

Very interesting though that they have issued a notice for 44AD case. 

I have also received same notice where TDS deudcted u/s 194J and we filed return in 44ad as business was in nature of "Other services n.e.s" Business code selected was 16019. 

How to response on this ? 

same as above and then wait for detailed questionnaire. engage a CA if required. 

Now they are asking for P/L and B/S u./s 142(1). Is it valid to ask for financial statement when return was filed u/s 44AD.
