@Rolisa jones When did you file? Did you efile or mail it? If you efiled was it Accepted? When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile. And check your spam folder for them.
When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc. What does it say?
Then the IRS is still behind processing 2020 returns. They still have 6 million left. You need to ask the IRS if they got your return and if they sent the refund yet.
Where did it say they will mail you a check?
