Where is my refund?

Waiting and not knowing the status of your tax return and refund can be frustrating.
Unfortunately TurboTax gets no information about the status of your refund.
In normal times, the IRS says that most filers get their refunds within 21 days from the time their tax return is accepted.
Many returns are taking longer now since the IRS did not process returns for a while and there is now a big backlog of unprocessed returns.
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. 
They are now taking phone calls with a limited staff but it's hard to get through.

If you efiled your return, have you confirmed that the return was submitted by TurboTax and accepted by the IRS?

If accepted, what does the IRS tracking web site say about the status of your refund?

If you mailed your return, you must print and mail it yourself. TurboTax does not mail it for you. You will not be able to start tracking your return until the IRS starts processing it.
