Cost that Turbotax Charges to File the State returns

I used 2021 Turbotax Deluxe CD. I filed my federal in February. Then when I began the California state filing, I paid $20. But on the payment screen it showed $20 but also showed $25 crossed out. I remember last year I paid $20 when I filed in February. A friend of mine asked me to help him do his taxes last year and he bought Turbotax Deluxe. He filed in March and Turbotax charged him $25. Why does Turbotax charge different prices to file the state ?

Please advise. Thanks and blessings !
