on the final tax summary the state refund amount is incorrect

I would suggest that you review the whole return, starting with the federal return.  TurboTax transfers data from your federal return to your state return. Before you begin troubleshooting your state return, go back through your federal return and make sure everything is correct.

 

After you review your federal return, select the State Taxes tab and review the state section. Pay close attention to the information, especially if you have made changes to your federal return. There might be new sections that need to be completed. 

 

You can also preview your return by following the steps below:

 

1. Sign in to TurboTax
2. Open or continue your return by selecting Start 
3. Select Tax Tools from the menu
4. With the Tax Tools menu open
5. Preview your entire return: Select Print Center and then Print, save or preview this year's return (you may be asked to register or pay first)
6. View only your 1040 form: Select Tools. Next, select View Tax Summary in the pop-up, then Preview my 1040 in the left menu.
