Assuming the bank rejects your refund because it is an
incorrect account, the IRS will issue a check and mail it to the address shown
on your tax return.
Or, if the return hasn't already posted to the IRS's
system, you can ask them to stop the direct deposit. You may call them
toll-free at 800-829-1040, M - F, 7 a.m. - 7 p.m.
