I am also the same issues. Never had the 'failed validation' problem efiling both federal and state around the same time (always file my taxes President's weekend). I'm using TurboTax Deluxe online version (same one as always) for 2024. My software is updated. I ran the online updates several times. I cleared my cache, cookies and browsing history several time. Rebooted. Nothing worked. And yes, I already paid for efiling state return fee (CA) as well. Can TurboTax expert assist - other than with recommendation to manually update of software that didn't work either?
