Was there a pandemic deadline extension for funding an IRA account for tax year 2022?

I requested the funding of an IRA account for tax year 2022 on the last day that taxes were due.  But my stock brokerage said that I missed the deadline and applied the funding to next year (2023).  I am on California west coast time zone and my stock brokerage time stamped with their East coast time zone.  Then I read later that Californians have automatic extension to file tax returns due to the pandemic situation.  Should I challenge my stock brokerage on the funding deadline?  Or just have to un-do this IRA funding since I missed the tax filing deadline?
