After you file

I understand that if the payments haven't been recieved by Jan. 15 (today), then I have to make a claim on the 2020 tax returns asap. What I'm confused about is why did I get the email that my funds were on the way, but I recieved nothing. Was this just a blanket email to all customers with no information checked? I would think TurboTax would've linked the payment information to the account I've used for over a decade now, to make sure my payment was indeed accounted for. So this makes me question the validity of the email and the trustworthiness of the program. Any answers beyond "the IRS..."?
