Hi I filed taxes 2021 and haven't received them yet it says it is on reviewing
Is that what the status shows when you look here on the where's my refund tool? https://www.irs.gov/refunds
With 2021 only being 2 years ago you should still be in the window of qualifying for your refund from what I see here https://www.irs.gov/pub/irs-news/fs-08-12.pdf .
I believe FreeTaxUSA no longer has any control over the document once it is submitted to the IRS, so I would continue to check the refund tool! Hope this helps give some info - a fellow FreeTaxUSAer
