I appreciate your efforts in trying some troubleshooting steps to get this banking error sorted out, vtalley13.
 

Error code 106 means QuickBooks is unable to locate your account on your bank or Financial Institution's (FI) website. This happens when the account is closed. You'll want to make sure you're using the correct bank's URL when connecting your account to prevent any error. Follow the steps below:

1. Login to your bank’s website and confirm that you have the correct login credentials.
2. Login to your QBSE account through a web browser using this link https://selfemployed.intuit.com/login.
3. Go to Banks Accounts page by clicking the Gear icon at the top.
4. In the search box, enter the name or URL of your bank.
5. Select Continue. 
6. Physically type the username and password you use for your bank's website.
7. Hit Connect securely.

However, if you have tried all the options matching your bank's name and still can't connect, or if your bank doesn’t appear, you can request support for your bank. Here's how: 

1. Click the Gear icon, then select Ban.
2. Enter Venmo from the search bar.
3. Select the Still can't find your bank link.
4. In the Bank name field, enter the full name of the account 
5. Paste the bank's URL in the field, then click Request.
