If you efiled, you should 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 it's not on the landing page, then scroll down to the section "Your Tax Returns & Documents" and expand that section.
If the info at the Tax Home confirms it was accepted (or if you mailed the return), you can use the "Where's My Refund" tool at the IRS website below to check on the status of your Federal refund.
https://www.irs.gov/Refunds
NOTE: When using that tool, be sure to enter the correct SSN and filing status. Use only the Federal refund amount, and not any total refund amount that includes a state refund. The amount to use is on your Federal Form 1040, Line 21a.
If the IRS tool says it is still being processed, and if it's been longer than 21 days since you efiled, or longer than 6 weeks if you filed by mail, we can tell you how to contact the IRS to inquire about the delay.
