Which itr form to be used ?

It does not mean you shuld have a real business setup to earn such income. As income earned thru Advisory services, which can be termed as a Profession, he can file ITR 4 but certainly not ITR 1.

Thanks,

Thanks for reply

He didnt prepare Balance sheet n all. 

Can we file ITR 2  and will show it as income from other sources and claim TDS deducted on that.

Since income as an advisor is a professional income, he have to file ITR-4 . 

You need to file only ITR-4 only under professional income
