The IRS began accepting tax returns on Jan. 29 and do to the backlog of early filers they are having to play catchup. I recommend just checking back to see when it updates.

The IRS issues refunds in about 21 days. But it is a case by case basis, you can check the status of your federal return here: https://www.irs.gov/refunds

Also, your federal refund can take longer than 21 days to process for the following reasons:

• You claimed an Earned Income Tax Credit and/or an Additional Child Tax Credit and filed before February 15, 2018.  It takes until the week of February 27 to receive your refund at the earliest.
• The IRS processed a refund offset.
• There were errors, inconsistencies, or missing info on the return.
• The return is under review.
• The IRS suspects identity theft or fraud.
• There's a Form 8397 (Injured Spouse Allocation) on your return.  It takes 11-14 weeks to process.
• You filed Form 1040-X (Amended Return), which can take 12-16 weeks to process.

TurboTax cannot research your refund and IRS representatives can only research your refund if it’s been at least 21 days since you e-filed, at least 6 weeks since you mailed your return, or if their Where’s My Refund? lookup tool tells you to contact them.
