@Missie7511 (and I assume you are filing single?)
1) check your bank statements from March through May, 2021 (February is too early)
2) check your account at the IRS website to see if it was issued (esp. the date it was issued as it would be in your bank account a few days later) and / or redeposited (i.e. not delivered to you)
3) if the IRS website indicates it was sent to you and you have no record of receipt, then you'll need to ask the IRS to trace the payment..... using the form in the link below
