I paid CA estimated tax for 2024 based on the calculation from TurboTax, but I'm still asked by TurboTax to pay tax underpayment for CA. Any solution for this?

TurboTax calculates the estimated tax payments based on 100% of the tax shown on your 2023 tax return including Alternative Minimum Tax (AMT).   These amounts may be different if you are a higher income taxpayer,

After awhile, the penalty disappeared! Everything is good.
