Foreign Tax Credit Carryforward

In past years starting in 2018 we had Foreign Tax Credit Carryforwards.

 

Do we carry forward all past years FTC Carryforwards or just the latest year?

 

Please see attached as it lists FTC taxes paid, the amount utilized, and the carryforward.  Just not sure if the carryforward is cumulative or just from the previous year.

 

Thanks,
