Incorrect calculation for top 2025 California tax bracket

TurboTax 2025 currently appears to be using an incorrect calculation on CA Form 540 for the top marginal tax bracket (>$742,953).
For example, given a single filer with a Line 19 taxable income of $1,000,000, TurboTax calculates a Line 31 Tax value of $104,854. This is incorrect, as per the 2025 FTB tax schedule (www.ftb.ca.gov/forms/2025/2025-540-tax-rate-schedules.pdf) and online calculator (webapp.ftb.ca.gov/taxcalc/), this should be $72,219.84 + 12.3% of the amount over $742,953, or $103,837.
From trying a few values, it appears TurboTax is incorrectly using a value closer to 12.7% as the top marginal rate, rather than 12.3%. This affects both the online and Mac desktop versions.
