Itr-2 ay 2019-20 - how to report unlisted shares cost of acquisition

I received a gift of unlisted shares from a non-relative during FY 2018-19. Value of the gifted shares valued using Rule 11UA does not exceed 50,000/- . So my query is regarding reporting the same in ITR-2 for AY 2019-20 - 

1. What should I fill in the column of purchase price of shares purchased during the year ?

2. What should I fill in the Cost of acquisition of closing balance of unlisted shares ?
