Income from partnership firm, but no business or profession - which itr to file - itr - income tax

I have profit income from partnership firm. But I dont have a proprietorship business or profession.  This year(A.Y 2018-19) they have removed Schedule IF(Information regarding partnership firms) in ITR2. Also in schedule AL(assets and liabilities), there is no section to disclose the investment amount in a partnership firm. Due to this most popular websites/articles suggest that partners should file ITR3(which makes sense).  But in ITR3, the NATURE OF BUSINESS section requires atleast one row to be filled. But I dont have a business or profession. I have only profit income from a partnership firm. Hence I am unable to file ITR3 as well. So I am unable to use both ITR2 and ITR3. Please advise how to proceed. Thanks in advance for your help.
