Taxation in case of job change

Pankhuri Jain (student ) (48 Points)

15 February 2021  
In FY 2020-21, till December 2020 I was getting professional fees and i used to take benefit of 44ADA

However, from February 2021 I switched my company and I am a salaried person now

How will I compute my tax liability now.
Can I still take benefit of 44ADA?
