Refund never sent?

Does someone want to explain to me what’s going on? The IRS released my refund for my on March 2. It was never deposited. I contacted TurboTax and was told they can’t help, I need to contact Santa Barbara tax payer group because that’s who takes out the fees. So I did. After 2 1/2 hours on March 4 I was able to reach a very rude representative who told me there “was an error in the system and I will have to wait 7-10 business days for the direct deposit.” Ok no problem. 7-10 business days came and went. I called back. Three days in a row I waited on the phone and my call was never answered. Finally, on the 4th day I was able to reach another rude representative. I waited and waited and waited while “she tried to gather information” finally, I was told there was a “code” and my refund was in reserve. I asked what that meant and what the code number was and if the code number was from TPG or the IRS. She couldn’t/wouldn’t answer me. I was then told that my refund was being sent back to the IRS. I asked why and she says “there is a code” and I still don’t know what it is or what it means. Mind you, I have received my state refund without issue. I don’t think I will EVER use turbo tax again due to their affiliation with TPG who is STEALING refunds and I am currently on the phone reporting all of this to the IRS.
