whether provision of section 44AD to be consider or section 44ADA

Hello Everyone. ..

There is a Work Contractor who receive a contract of Rs. 40 lacs

As per GST, a work contractor supply is treated as a supply of service and not the supply of goods.

so at the time of filing of income tax return whether such contract income to be consider u/s 44AD or u/s 44ADA, as Indirect Tax is considering such supply as supply of service.

Further provision of section 44ADA also specify that a person engaged in profession of Engineering or Architect , section 44ADA had not used the word professional but used the word engage in profession.

so please help me to whether 44AD to be consider or section 44ADA? ???
