I have not received my stimulus check, I was told it may be because of the way TurboTax handled my direct deposit.

If you had your TurboTax fees paid from your federal refund, the IRS does not have your direct deposit information. The IRS will send it to the account shown on your tax return which was for the 3rd party bank that took your fees from your refund. The bank will decline the deposit and the IRS will issue a paper check and mail it to you at the address shown on your tax return. 

See why the IRS says it couldn't be changed: 

To help protect against potential fraud, the tool also does not allow people to change direct deposit bank account information already on file with the IRS.

If we issue a direct deposit and the bank information is invalid or the bank account has been closed, the bank will reject the deposit. We will then mail your payment as soon as possible to the address we have on file for you. Get My Payment will be updated to reflect the date your payment will be mailed. Typically, once the payment is mailed, it will take up to 14 days to receive the payment, standard mailing time.
