Which ITR use having income from job work or project base work for A.Y 2019-20?

My uncle is doing a small Real Estate Construction Business. He has filed his IT Return as Proprietor U/S 44AD till F.Y. 2017-18 with closing stock of Rs. 35 Lakh. He is now doing a project with Mr. X under a joint agreement but without establishing any partnership firm. Is he allowed to file his IT return U/S 44AD as capacity of partner? If so then the proportionate sale amount should be shown or the gross sale value will be entertain and how show previous the previous closing stock ?

Query is whether the XML file generated thru ITR2 IT untility downloaded from efiling portal, should contain income under all prescribed and filled in different sheets or not. It is necessary to know as it does not show income under heads where income is actually filled in relevant sheets. Now before uploading it is required to be clarified , as once uploaded it may not carry complete and correct return. Also in some sheets on pressing validation button , one one side it tells 'this sheet is correct, and on other side it keeps on circling which is never ending. what is this is not clear. . In such situation is that sheet is validated or not .

Pls share if someone is encounterinf such situation
