Get your taxes done using TurboTax

I am having the EXACT same problem, same software, same platform. How do I get out of this doom-loop?  TurboTax Deluxe (from a CD), Windows 11, all updates, great internet connection, rebooted, keep getting same message "Can't confirm if Intuit Filing Center received your returns". Tells me to take a break and check back in an hour. I have done that 5 times. Called Customer Support, they have no clue. Somebody PLEASE HELP!
