An efiled return normally takes up to 21 days for most people, but it's not uncommon for it to be further delayed if the IRS has to review anything or needs more info. Sometimes they will prepare a notice/letter to mail.
If you filed by printing and mailing, it can take several weeks to process.
Here are some things you should check:
If you efiled, double-check to be sure the return was efiled successfully and accepted.
If you used Online TurboTax, you can sign into your Online Account and check the efile status at the Tax Home. If you used desktop software, you can check from within the software.
If that showed it was accepted, (or if you mailed a paper return), you can use the "Where's My Refund" tool at the IRS website below to monitor the status of your Federal refund.

What is displayed there about your refund? Are there any messages about a delay or needing more info?
Here are some tips when using the IRS "Where's My Refund" tool:
https://www.irs.gov/Refunds
- If you efiled, be sure you have waited at least 24 hours after acceptance before using the IRS WMR tool. If you mailed a paper return, it won't show up in the tool for at least 4 weeks or longer.
- Be sure you enter the correct SSN and filing status.
- Be sure you are using only the Federal refund amount. Do not include any state refund or any total refund or net refund (Fed and State) that TurboTax may have provided on a screen.
- Look at your actual Federal return to get the Federal refund amount, i.e., your Form 1040, Line 35a.
