In TurboTax Online, in the left-side menu, click on Tax Tools > Tools, then choose Delete a Form on the pop-up menu.
When the list of forms appears, look for Form 8915, and Delete it from your return.
Then close the program, clear your Cache and Cookies and this should resolve your issue. I assume you answered NO in the interview when asked if you had a Disaster Distribution?
