I'm sorry, but you can not change your refund method once your tax return has been accepted.
Your refund will be rejected by the bank and will be returned to the
IRS. You will eventually receive a paper check from the IRS, mailed to
the address you entered on your return. Expect that to delay your
refund by at least another two weeks.
If the return hasn't already posted to our
system [at the IRS], you can ask us to stop the direct deposit. You may call us
toll-free at 800-829-1040, M - F, 7 a.m. - 7 p.m.https://www.irs.gov/help-resources/tools-faqs/faqs-for-individuals/frequently-asked-tax-questions-an...
