Adding interest income from Charles Schwab. TurboTax has the Charle Schwab int listed there, I click add, goes to next page I click add, it goes back to previous page

Did you enter your interest income manually or did you import a statement from Charles Schwab? 

Each page that you access should be providing information and prompting a next action. 

 

If you are using TurboTax Online, go back to the Income section, Investments and Savings. You will see a list of all of the interest items entered. If any of them were accidentally entered twice, delete the duplicate by clicking on the trash can icon that appears next to the "Review" or "Edit" button.

 

See this help article for more information about entering interest income.
