The 1099-INT form (Box 1) received from my broker sow interest income of $.09, yet the TuboTax summary page shows $2106. Where did the number come from?

Unless you had another 1099-INT, there is no way to tell where that amount came from. 

In any case, do not report a 1099-INT that only shows $.09 of interest income. Delete that 1099-INT from the tax file.

See: How do I delete forms in TurboTax Online?

After deleting that 1099-INT, log out of the program. When you log back in, use the Delete a Form tool (List of Forms in My Return) to confirm it has been removed from your return. 

Check again to see if the tax summary still shows $2106 ( or another incorrect amount) - if so, update this post with a comment and additional details.
