I entered the wrong bank account information (or I made an error when entering my bank account number), how can I fix this? – SoFi

Log into your SoFi account and click on "Missing Information".
Click on the blue "Back" icon in the bottom left (not the browser back button).
The "Let's Link Your Bank Account" page should appear.
Select "Enter Account and Routing Details".
Enter the desired new bank account number/information and then click "Next".
The "Your Account Has Been Linked" page should appear, click "Next".
On the "Would you like to enroll in AutoPay?" page, select "Yes" or "No".
1. If "Yes" or "No" was selected, you should see a confirmation "Sit Tight" page.
That's it your bank information has been updated.
