I put my account number in wrong when i filed my taxes

The bank will reject the deposit due to the incorrect account number.  The bank will send the federal tax refund back to the IRS.  The IRS will mail a refund check to the address on the tax return.

No, once your tax return is submitted and accepted, you can't change the direct deposit account for the refund. 

In a case where the direct deposit account is wrong or closed, the refund will bounce back to the IRS and they will issue the refund again as a mailed check, which will be sent to the address on your tax return.

If your refund is sent back to the IRS—- make certain that the address you entered on your Form 1040 is correct.  And…open all mail, even if it looks like junk mail.
