Failed Validation efiling 2024 Turbo Tax Deluxe online version

Hi.  I just finished completing my tax returns for 2024 and wanted to efile them.  I keep receiving failed validation error messages when transmitting my returns (efiling), something I've never encountered before with past years Turbo Tax versions.  I have WIN 11 OS, and am using TurboTax Deluxe online version.  I tried clearing my cache, cookies and browsing history, shutting down my computer and restarting, it still gives me the same error message.  Please assist.
