Capital Loss Carryover figure on main form is 0

I'm doing my taxes for 2021 and I have imported my stock transactions for 2021 into TurboTax.  I've entered the figures from my 2020 return as requested to calculate my capital loss carryover.  I had a large capital loss several years ago that I'm amortizing each year.

 

Now on the main screen for my 2021 return, the screen where you select which tax area you want to delve into, after having entered my loss info it says my capital loss amount for 2021 is 0.  Huh?  I checked the figures from the 2020 return and they appear to be correct.  So why is it saying 0?  I'm entering losses as negative numbers and gains as positive numbers.
