If you're trying to check the status of your refund:

As xmasbaby0 said, “The IRS guideline is that refunds are issued within 21 days”, provided they are:

• Electronically filed 
• With Direct Deposit, 
• And provided there are no other issues.

To check your tax refund status in TurboTax, 

1. Sign in to your account and 
2. Go to the "Tax Home" or "Order Details" screen 
3. It'll tell you if your return was accepted.

If you want to know the status of your tax return,  you should use the 

IRS Where's My Refund website.

 You'll need

• Your Social Security or individual taxpayer ID number (ITIN)
• Your filing status
• The exact refund amount on your return

Things that can delay a refund:

TurboTax can only give an estimate for when the refund will be issued.

Only the IRS and your State control when and if a Federal or State tax refund is Approved and Issued.

Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund.

If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

If accepted by the state use this TurboTax support FAQ to check the state tax refund status - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-refund/track-state-refund/L3jgO8PGs_...

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
