In 2020 I have a capital loss; I was expecting a negative amount in the capital gains field, but it is 0. Does this seem right? Will the amount be available for future?

It is also asking me to go to the years back (2019, 2018, 2017) but all are 0. I am confused as to why it is referencing previous years (to apply the loss to) or if that the amount was applied to this year and that it would be carrier forward.
