Can't Edit "Bank or Brokerage" field for a 1099B Entry

I entered some prelim data in TTax with some placeholder names on the "Bank or Brokerage" field for my 1099Bs.  I need to edit the name used for the 1099B but it appears to not be editable while the DIV and INT entities (Payer Name) are.  I discovered TTax will consolidate the listing of a similarly named Payer which makes things neat and tidy, but not sure whether it will pull in the 1099B or not.  In the end I want the recording on the final tax form to be the Bank or Brokerage name I choose, not my placeholder.

 

I see no way to edit it and I don't even see a way to delete an entry so I could restart the entry which I don't want to do but I could as a fallback.

 

Am I missing something here that the name for the 1099B is locked once you enter it?
