Restricted stock units in itr ay 2019-20

It being investment, need not be declared till sold. 

If at all you wish to declare file ITR 3 with complete balance sheet. Otherwise ITR 1 or ITR 2 will be applicable as per your other credentials.

Thanks for the update.

Do you mean i no need of declaration of these RSU ( 25%)  in ITR even though they are vested during FY 18-19 but not sold  ?  My employer has deducted withholding tax and shown in From 16 as perquisites in form 12B A.
