I cant finish my return, the site wont allow me to enter a date in the "fix my return" page. It just returns me back to a blank page.

Make sure to add the date acquired to the box at the top left of the screen, then click continue. No need to enter it in the form. Continue to add the date acquired and click continue until its fixed, as it may be needed on multiple stocks.

You may need to go back to where you entered your stocks, since you are getting a blank page. Please see, this TurboTax FAQ, Where do I enter investment sales?

I have done that ten times, once you click continue it takes you back to the same page asking for the date again. It is not functioning correctly
