Why has my taxes said accepted from March 15th. But I still haven't got my refund

[Critter-3]

Your situation is not unusual at all.  Millions of people are in the same boat this year.  Long delays at the IRS are due to Pandemic-induced staff shortages, large backlog of unprocessed return, extra duties of providing the stimulus payments, last minute changes in tax laws, etc.   Delays are even longer with mailed returns or anything that requires any manual processing or additional investigation.  Of course, there are some things you should check:

If you efiled, double-check that your efiled return was indeed accepted.  If you used Online TurboTax, log in and go to the Tax Home and check the efile status, then use the tool below.

Here are some tips when using the IRS "Where's My Refund" tool:

https://www.irs.gov/Refunds

• 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.  
• Also be sure you are using the Federal amount before any TurboTax fees are taken out (if you chose that option.)
• Look at your actual Federal return to get the Federal refund amount, i.e., your Form 1040, Line 35a.

• You can also try phoning the IRS refund hotline.  I've seen it work for some users when the WMR tool didn't.  800-829-1954

As of June 30th there were 35 million US income tax returns that had not been processed and estimated only 3% of phone calls were being answered. Verify that here

The IRS is seriously behind in processing 2020 tax returns.  This is due to many factors, such as the pandemic, completing processing of millions of 2019 tax returns, stimulus payments, unemployment compensation exclusion tax refunds., changes in the tax code by Congress in the middle of the 2020 tax season and the like.

Millions of taxpayers have not yet received there federal tax refunds.

As of July 9, 2021, we had 16.4 million unprocessed individual returns. Unprocessed individual returns include tax year 2020 returns such as those requiring correction to the Recovery Rebate Credit amount or validation of 2019 income used to figure the Earned Income Tax Credit (EITC) and Additional Child Tax Credit (ACTC). This work does not require us to correspond with taxpayers but does require special handling by an IRS employee so, in these instances, it is taking the IRS more than 21 days to issue any related refund and in some cases this work could take 90 to 120 days. If, as a result, a correction is made to any RRC, EITC or ACTC claimed on the return, the IRS will send taxpayers an explanation. Taxpayers are encouraged to continue to check Where’s My Refund? for their personalized refund status and can review Tax Season Refund Frequently Asked Questions.

What you should do: If you filed electronically and received an acknowledgement, you do not need to take any further action other than promptly responding to any requests for information. If you filed on paper, check Where’s my refund? If it tells you we have received your return or are processing or reviewing it, we are processing your return, but it may be under review. We’re working hard to get through the backlog. Please don’t file a second tax return or contact the IRS about the status of your return.
