The following solved the issue:
If you are using Desktop Software:
1. Open TurboTax software, then open the file you are working on.
2. Open the "forms" tab at top left.
3. Scroll down to where the banking information is and the routing box will be yellow with the routing number and the word routing number behind it.
4. Clear the box and move the cursor out of the box, then re-enter the cursor in the box and enter your routing number and that should fix it.
