If i entered the right account number and bank name but the wrong routing number will my check still be deposited?

[Critter · Accepted solution]

No it will not ... the refund will be converted to a paper check mailed to the address on the return ... this conversion process can take 3 weeks or more.

The routing number is the bank number and both have to be valid.  In most cases, once the IRS has accepted your return (or you've already mailed it), there's not much you can do.

If the info you provided is for a closed or invalid account, the government will mail you a refund check.

If you haven't filed yet, you can still change your bank account info for direct deposit.

On filed returns in pending status, wait until it's either accepted or rejected before taking action. If rejected, you can update your account and any issues that caused the rejection. Open your return in TurboTax and go through the File section again to update your bank account before re-submitting your return.
