Unfortunately there is nothing further that you can do other than wait and keep checking the IRS every week for an update.

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 3, 2021, we had 16.8 million unprocessed individual returns in the pipeline. Unprocessed 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. 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.

Who took it out incorrectly?  If you are getting a big refund each year you can change your withholding to have less taken out of your checks so  you get more each month and not let the IRS hold your money all year.  

exactly what wording do you get when you use the IRS WMR tool?  the IRS is far behind (more than 90 days in some cases) in issuing refunds especially if you filed before Turbotax was updated for tax law changes. if you claimed certain credits using 2019 income, all those returns must be processed manually. Nothing can be done to speed up your refund.  Turbotax did not take your money. 

1) you filed before tax law changes were reflected in the software - even early  filers using a professional had the same issue

2) you enter info to calculate estimated tax payments using the 2019 app which had no way of knowing there would be tax law changed in 2020 or you submitted a w-4 based on pre 2020 tax laws.
