I believe my account number I entered is incorrect to receive my return. Would TurboTax have prompted me if it was incorrect?

There's no way TurboTax would know if the number you entered was correct or not.

If you are speaking about your account number for your refund to be direct deposit or your payment to be directly debited, no TurboTax has no way of knowing if your account number is accurate.

If your account number is inaccurate and you are expecting a refund,

• If the banking information you originally entered was wrong, most likely the direct deposit will be rejected and it will be sent back to the IRS and they will in turn print and mail a check to the address listed on your return. 

If a significant amount of time has passed and your refund has still not been returned to the IRS, you can file Form 3911Taxpayer Statement Regarding Refund to request a trace on the refund with the IRS. This usually takes 90 days to complete.
