this doesn't sound right at all. The IRS doesn't do refund traces on funds that aren't even paid yet. These are PENDING deposits, you don't even know for certain that you didn't get it yet. The IRS is not going to trace it at this point, no matter what someone on the phone supposedly told you.
i would follow the instructions to contact TurboTax and ask them to confirm what is showing on their end (you will likely have to tell them what it should be, and they can tell you if it matches or not)
If it doesn't, the more likely issue is some type of identity theft in which case the payment will probably be returned. You haven't even given it enough time for it to correct itself. You're jumping the gun here.
Contact TurboTax, see what they have on file. It's NOT possible for the information to change en route. It is possible for there to be an entry error on your return (which I assume you already checked the 2020 tax return that you filed and verified that the information matches) or someone else filed before your 2020 return was processed and then you may have a theft issue.
TurboTax WILL confirm with you if the last 4 digits you provide match what they have on file. That would be better use of your time. Again, it's not lost yet! You haven't given it a chance to bounce back and be re-issued IF it was misdirected.
If you didn't file 2020 yet, then identity theft is what you are almost certainly dealing with.
