Capital gains: selling inherited house floors

I'm 62 years old and retired from a bank manager's post in August 2023. Here's my situation in detail: my parents purchased a residential built-up property of 149.10 sq. mt in East Delhi in July 1996 for 4.96 lakh.

After their passing, I inherited the property through a registered deed, will, and mutation was completed in February 2020. The 2001 valuation of the property was 38.45 lakh.

Under a builder agreement, the four independent floors were constructed on the property between July 2019 and July 2021.

As part of the arrangement, the second floor was sold to the builder in July 2021 for 56 lakh, but I did not make any direct investment towards construction costs of the property.

The ground, upper and first floors continue to be with me. However, I sold the top floor in July 2024 for 65.65 lakh.
