Income tax under 44AD

I am an online educator and my company has provided my earnings by deducting TDS under 194JB. 
So should I file ITR under 115BAC (New Tax Regime)?

Also under the head of Income u/s 44AD, what percentage should I consider for showing as income. Should we consider 50% or 30% or is there any standard recommendation to be followed. 

pls guide.
