IRS representatives are the only ones that are able to research the status of your refund if your return was accepted (received) more than 21 calendar days ago. Call them at 1-800-829-1040, but prepare for potentially long wait times.

Additionally,
taxpayers who claim the Earned Income Tax Credit or the Additional Child
Tax Credit may experience a refund hold. The IRS expects the
earliest EITC/ACTC related refunds to be available in taxpayer bank
accounts or debit cards starting February 27, 2019, if these
taxpayers chose direct deposit and there are no other issues with their tax
return.
