After transmitting returns, no email or text confirming that my returns have been transmitted

I have transmitted my returns, but I have not received an email or text confirming that my returns have been sent to the IRS. When I go back to TurboTax, they say that I  haven't transmitted my returns. I have transmitted my returns 3 times, and each time TurboTax says they have transmitted my returns, but I get no confirmation that they have sent my return. It's been 3 days since I originally transmitted my returns.
