After you file

It's kinda hard to explain it but file says I should recieve the third stimulus and money that I got accepted includes federal tax and third stimulus check. But when I checked the money I only recieved federal tax money and third stimulus check wasn't included. After I recieved money, I checked the website and it says I recieved all the money. I try to make accont and log in to IRS account but it says my ss number did not found.
