Which ITR to use

Could you please tell as to where to fill the income receipts?

shall I show the receipts under salary head?

1) Income will be form Business & profession ,  ( He is on contract no employer & employee relation )  

2) Total  amount  received  -  total  expense incurred for the purpose of  earning  this income 

    ( expense with documentary evidence )  personal expense not allowed as an expense 

3)  ITR3 / ITR4  check  out .   

receiving 60,000 pm and TDS is deducted u/s 194 J 

Will ITR 4  be the correct return ?

There is no other source of income, will it be shown under Section 44ADA in ITR 4?

If it shown u/s 44ADA in ITR 4, then 50% of receipts will be treated as income In that case, still there is a need to maintain the documentary evidence of expense?

Total annual income = 60,000*12=720000, in this case 360000 will be offered as income.

Is this the correct approach?

What  is your  profession ?. Are you filing  ITR for  F.Y 2019-20 ?. 

Itr 4 is ok  you can take 50% as pressumetive as per your proffession which  I don't
