What do you mean by "as a result"? As a result of what? The amounts you listed on the 2020 Capital Loss Carryforward Worksheet would not result in the loss not carrying over to 2021.
This has not been an issue with TurboTax. I did a test, with the same amounts that you gave on the 2020 Capital Loss Carryforward Worksheet, and the loss carried over to 2021. The problem is probably in 2021, not 2020.
Are you sure that the loss didn't carry forward to 2021? What is on line 6 of your 2021 Schedule D? If line 6 is -25,154 the loss did carry over to 2021. If line 6 is blank, the most likely cause is that when you started your 2021 tax return you did not transfer information from your 2020 return, or you transferred from the wrong 2020 file.
To correct the carryover, yes, you will have to amend your 2021 tax return before you start your 2022 tax return. When you start your 2022 return, make sure you transfer information from the amended 2021 return, not the original 2021 return. However, you do not have to wait for the IRS to finish processing your 2021 amended return before you file your 2022 return.
