After you file

your banking info is on line 20  A and B of your 1040 it will clearly show your routing and account number this is part of your tax documents  IRS should be able to see this info SBTG site clearly states IRS will be handling these direct deposits. my plan is if i don't see DD tomorrow I will check my status once the IRS tool is up there saying Friday the 17th you're supposed to be able to update banking info as well. My understanding IRS should have your DD info on your 1040
