Only direct DEPOSIT info is written on the form 1040 ... but if you owe the DEBIT info is never on the form 1040.
If you tried to efile and it was rejected then any bank info you entered is void and null. If you must mail in the return you need to make a payment. When you mail in the return you need to send a check with the 1040-V that prints out OR make other payment arrangements like paying directly online at www.irs.gov/payments.
If the correct (I stress "correct") routing number and account number are on the paper return you will be mailing to the IRS, then you do not need to write a check. However, I would suggest you write and send a check with your mailed return, after you blacken out the account/routing numbers on the return. When mailing your return things happen pretty much at the same pace regardless of how you pay any taxes due.
