How can I change my bank information so can I receive payment from the irs in the future ?

Your banking information cannot be changed after your tax return has been filed and accepted.

Banking information does not go from TT to the IRS until you file your 2020 tax return and it s accepted.  You enter/change banking information in the FILE section before you file your 2020 return. Changing it on the TurboTax site does not do any good until you file your return.  If they manage to send out stimulus checks before you can change your information, we hope the IRS provides a way for you to change it with the IRS.  If your check goes to a wrong or closed account, it will be sent back to the IRS and then the IRS will mail a check to the address on your tax return.

The IRS has your bank information based on what you have entered on a federal return with direct deposit of a federal tax refund.

When filing your 2020 federal tax refund and you have federal tax refund, when you select direct deposit of the refund you will enter the bank routing and account number.

If another stimulus payment is authorized by Congress and the President the IRS may have linkage on their website for entering bank information.
