Hi there,

For year-over-year comparison purposes, you can enter 2020 amounts on Screen 48, Prior Year Summary. 

Most carryovers should be entered on the screen/activity they relate to, so the program can track these more granularly. For example, carryovers of prior year unallowed passive losses from a Sch E rental would be input on Screen 18, for the property that generated the loss. 

Capital loss carryovers are similarly entered on Screen 17 - you can click the button or hyperlink to jump to the Carryovers/Misc Info input:
