How to edit an imported stock item in premier version?

I am not aware how to edit the title of the stock or IRS form 1099-B entered by importing the information from the financial institution.

You do appear to be able to edit the title when entering the IRS form 1099-B information by summary information instead of each individual transaction.  

Create a .PDF of the IRS form 1099-B to upload into TurboTax Premium Online.  Follow these steps.
