F1 Visa, current employment section

Hi,

I am filling out DS-160 and I am confused that what should I mention in current employment section because I was employed with an organisation from past 2.5 years and I left my job in Oct 2018 and since then I have been doing freelance work it's mostly like I go to technical colleges and take technical workshops
So my job is not fixed but the money I am earning will reflect in my ITR. So, can anyone please guide me that what should fill in DS-160 current employment section as I don't have a fixed organisation name, address and salary.

Thanks
