Actually I found the answer myself and downloaded an update patch. This is where to find it...
1. Click on Help Center (UL menu bar)
2. Click on Support
3. Enter "Check for Updates" in the search a question or keyword field
4. Scroll down & click on "Manually Update Turbo Tax for Windows Software (Basic, Deluxe, Premier, Home & Business"
5. Under the heading "Turbo Tax 2020 Individual-15.1", Click on #2 to download the 189MB Update
Follow download process instructions. I reopened the Turbo Tax program and was then able to complete the electronic filing and received a confirmation message.
