How to report sale of two foreign real estates (personal property) realized during the same tax year, one with a gain and the other at a loss?

Me and my siblings sold two foreign real estates (houses) during 2020, which we owned jointly as personal property, with a capital gain on one of them and loss on the other.

How can I report my share of the capital gain and loss in my 2020 tax return so that I pay taxes on the difference?

Many thanks
