Itr form for a freelance copywriter

I am an individual, resident tax payer. I take up freelance copywriting assignments-- creative copywriting for brands, content development for websites, social media etc.

I operate at an individual capacity and not as a registered business. And my income from these services doesn't exceed 1.2 Lacs for AY2019-20.

I also have income from interest and property.

Should I file my returns using ITR1 or ITR4? And if it is ITR4, which presumptive taxation scheme does my services fall under? The business codes aren't specific. 

Kindly clarify. Much thanks.
