Why did my status change from accepted to pending

When you initially file your return, the IRS will accept the return. As as they process your return, the status will change.  Most refunds from e-filed returns are processed in about 21 days, although some returns take more time to review.  You can check the status of your refund at the IRS Where's My Refund? site.

• You'll need your Social Security number or ITIN, filing status, and the exact amount of your refund to check your status. You'll find this on the first screen after you sign in to TurboTax.
• If you mailed your return, wait 4 weeks after mailing your return before using the tool.

If it's been over 21 days since your e-filed return was accepted, you can call the IRS to check on your refund status.
