no way to change DD info since the check is supposed to go out in less than 2 weeks assuming Congress quickly overrides Trump's veto. the payment will be sent to the same a/c as the previous one. since that a/c is closed the check will be returned to the IRS to issue a paper check which will go to the address on the last timely filed return. if you've moved file form 8822

also file change of address with USPS.
