What's the impact of Califronia tax deadline extensions on 2023 estimated tax payment?

The deadline is extended to 11/16/2023. If I didn't make 2023 estimated tax payment on the first 3 quaters, will the penalty be waived if I make enough payment on the last quarter?

@delvalle it depends - you can complete form 2210 to determine that. or wait for the IRS to bill you.

Just found this (https://www.kiplinger.com/taxes/california-tax-deadline-extensions), since 2023 estimated tax is also extended to 11/16/2023:

- If you have estimated tax payments due this year (2023), the IRS extended tax deadline applies to payments that would normally be due on April 18 (that was Tax Day for most people), June 15, and Sept. 15, 2023.
