I found a solution, but this is definitely a bug that TurboTax should fix.
When in the screen where you are viewing your Transaction ranges, click View in top menu bar, then Forms. This will open the 1099-B worksheet.
On the left side-bar there will be Cap Asset Sales (1), etc and it will mark which is not done.
You can open these forms and enter the details, I started doing this and then hit Close Form (until all forms were closed) to check progress, and when it sent me back to step-by-step, I was able to Review and see the transactions for what was previously missing in UI and edit as normal.
