Under Turbotax State and Local Tax Refund Summary, the 2019 State Refund Amount is doubled, does anyone know why ?

This may be your issue - 

There was an issue with 1099-Gs (used for state refunds and unemployment) being accidentally duplicated, so the amount was doubled as if you had entered it twice.

The issue has been fixed, but if the 1099-G got duplicated, you will have to go manually delete the extra form. Please check for this, and come back if it is not the case.

To find and delete the extra form, do a Search (upper right) for 1099-g, and click on the jump-to link (Mac users must find 1099-G in the Topics List).

This should show you a table of 1099-Gs that were entered. Edit them one by one to see what they are, and if you find the duplicate, just delete it using the Delete button or the trash can icon.

If that does not work for you, you can do the following:

*** Desktop***

1. go to View (at the top), choose Forms, and select the desired form. Note the Delete Form button at the bottom of the screen.

*** Online ***

1. go to Tax Tools (on the left), and navigate to Tools->Delete a form

2. delete the extra form (if one)
