The IRS says 9 out of 10 filers who efile and choose direct deposit will get their Federal refunds within 21 days after being accepted. Some returns are processed fairly quickly, while others require additional processing due to specific items in the return. Some are pulled at random for more thorough investigation.
Did you efile, or did you choose to print and mail the return? If you filed by mail, it can take about 6 weeks to get a Federal refund.
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 that showed it was accepted, you can use the "Where's My Refund" tool at the IRS website below to monitor the status of your Federal refund.
NOTE: When using that tool, 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.
To track a state refund:
If it's been longer than 21 days, and the IRS tool says it is still "being processed," then you're sort of in limbo.
In "normal times" you could speak to a live agent at the IRS to see if they can tell you anything about the delay. Perhaps they were planning to send you a letter or need additional info. Unfortunately, due to the Coronavirus situation and many IRS personnel sheltering at home, a lot of processing at the IRS has been suspended, correspondence is markedly limited, and their call centers are all but shut down for the time being.
The IRS says on their website:
"To protect the public and employees, and in compliance with orders of local health authorities around the country, certain IRS services such as live assistance on telephones, processing paper tax returns and responding to correspondence are extremely limited or suspended until further notice."
