My tax return was accepted Feb. 13 and I still have not received it. I did my return efile with direct deposit. Is there a reason it still hasn’t come?

The IRS says that for most taxpayers (like 90%) on average it takes about 21 days from acceptance. In reality, some take longer. Check your refund status on the IRS website
