How can I change the estimated taxes applied from last year?

In California Form 540, line 72, it shows we have applied last year's refund to this year's estimated taxes. Last year's refund in TurboTax turned out to be incorrect and we paid the state directly.

 

Now, however, TurboTax is showing that as a refund for 2020 and being applied to 2021 estimated taxes. The amount listed is too high and is creating a false refund for 2021 taxes.

 

How/where do I change this?

 

The form does not allow any changes and the Help Center hints at it coming from the Federal form. I cannot find it anywhere where I can actually change it to $0 (correct amount).
