Wife and I bought a double lot (120' by 150') in 2015 and have lived in it since. We sold the lots separately in 2023 and bought a new house. How do we record this?

The house is entirely on one lot by we used the whole property daily for recreation, gardening, etc. and it is less than half a hectare. How do we record this in our tax return? We have a survey of the property that can help explain, do we add that to the tax return as well?
