Long Term Capital Gains on sale of Flat

I booked a flat in the year 2012 for a consideration of Rs. 5200000. Periodic payment was made as per the progress of construction. Final installment was paid in December 2017. I took possession of the flat in March 2019 and disposed it in May 2019 for Rs 5800000. There was no registration of the flat in my name at any time. What is my Capital Gains liability in this case considering that payment was made in installments over a period of about 6 years before possession in March 2019 and holding for just about 1 month before disposal in May 2019?

Please advise.
