How will turbo tax give me my second stimulus check

[xmasbaby0]

TurboTax will not be giving you a stimulus check.    The IRS will be sending out stimulus money.  The IRS will use the banking information they already have on record for you.

BANKING INFORMATION

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 is accepted. The IRS will begin to accept  and process 2020 returns at the end of January 2021.

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 and the IRS processes your return.   If they manage to start sending  out stimulus checks before you can change your information, we hope the IRS provides a way for you to change it with the IRS. Right now there are no new guidelines.   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.

especially the part about what happens if payment isn't issued by 1/15/2021.  It appears e-filing won't open until after that date.
