My accountant did my taxes 3 weeks ago on here and nothing has updated on the IRS website. How do I found out my status?

Paid tax preparers are not allowed to use TurboTax.   If you paid someone to prepare your 2020 tax return they should have  used professional tax software and provided you with a copy of your return.   Then you can use the IRS site to check on your refund----if the preparer filed it.

 “21 days”  is not a promise from TurboTax or the IRS.   Many refunds are taking longer during the pandemic.  The IRS is backlogged —-they are still trying to process millions of 2019 returns; they received millions of e-filed on the day they opened for 2020 returns, and now they are burdened with sending out another round of stimulus checks.   

Some delays are resulting from incorrect amounts that folks entered for stimulus checks they received.   Many people have been confused by the recovery rebate credit and completed it incorrectly.  The IRS may delay your refund while they cross-check to see what you received.

First, check your e-file status to see if your return was accepted:

Once your federal return has been accepted by the IRS, only the IRS has any control.  TurboTax does not receive any updates from the IRS. Your ONLY source of information about your refund now is the IRS.

You need your filing status, your Social Security number and the exact amount  (line 34of your 2020 Form 1040) of your federal refund to track your Federal refund:

If you chose to have your TurboTax fees deducted from your federal refund, that will take some extra time, while the third party bank handles the refund processing.
