Filing income-tax return for current asst year 2019-2020

Dear Sir/Madam,

I had been regularly filed Income-tax return up to  Asst Year -2013-2014. after which I have not filed returns for the subsequent years due to discontinuance of business.

Now I have running small kirana shop (Retail ) in our area and getting income , Hence I intended to file Income -tax return for the current asst year 2019-2020. Is it possible to file ? 

Kindly guide me in this regard.

I am anticipating your responses.
