Refund still under review

Refund still under review, I filed my tax refund in late January as recommended by TurboTax to file early. Due to the second stimulus check error like thousands of Americans I did not think I was going to get it therefore I claim the rebate recovery credit. I received A code 151 return under review . I received a notice in the mail that stated the address needed to make an adjustment on my tax return due to claim in the rebate recovery credit However it was received after I filed. Notice continued to say if I agree do nothing if I disagreed file an appeal I had any questions or concerns to call. About a week and a half ago  I received a partial refund I have a small amount which basically was the federal that was withheld. So I called TurboTax TurboTax could not tell me anything so I called the IRS after waiting on the phone for 10 hours I finally got through and they could not tell me anything.  This is about a week later and I still do not have a status  change on the IRS website no additional money has been deposited into my account and I don't have any other information other than what I have received. I do not know what to do this is very stressful . Can a TurboTax agent please assist me with finding out where my refund is?
