You can verify your tax return was in fact accepted by the IRS by clicking on the links below, if you did not receive the email confirmation:
I’m having the same issue, I filed 2-28-2020 and I got a text but no email. The IRS website states my information doesn’t match when I try tracking my refund and state says it hasn’t been received. What do I do now ?
First, check your e-file status to ensure your tax return was successfully e-filed. Refer to the following TurboTax FAQ for assistance: How do I check my e-file status? - Community - TurboTax
If you don't see a status, go through the TurboTax File section again. Be sure to go all the way to the end and select Transmit my returns now.
If your status shows accepted, then the IRS has received your return. If Where's My Refund does not display your refund status, try calling the IRS Refund Hotline at (800) 829-1954.
