After you file

What's the purpose of this form? If I agreed to have my turbo filing fees to be paid for by your bankers which agreement was to direct deposit my refund into my checking account. STPG said that turbo gave them the wrong routing number so they mailed an cashiers check. It's been three months and I haven't received anything. Error isn't on my end( not my fault). So why the need to pay more Money to notarize this form and email it. Which rep said to email it to a total different email then what's on the form. If I was to notarize this paper then the fault is on me if I end up not receiving the check then what?????....
