Resident of San Diego, CA, is Turbo Tax aware of the Tax Deadline Extension for San Diegans? Do I need to file or pre-submit anything in to utilize the extended date?

[DoninGA]

No, you do not need to submit anything.  The IRS will know based on the address of your tax return that the filing date of on or before June 17, 2024 is in effect.

However, if your tax return has a tax refund you can file your tax return at any time on or before April 15, 2027 without penalty.
