My tax return is still being processed, even though I have applied in the end of February. What should I do?

Have you checked the IRS website?  Although TurboTax tells you that you should receive your refund within 21 days—per the IRS estimated wait time—, there is no guarantee that it will not take longer.  Once you file your tax return, only the IRS can determine how long it will take to process your refund.  Some people are experiencing longer waits as the IRS reviews their returns to prevent identity theft and fraud. Although it is very frustrating, there is no way to speed up the IRS.
