Bug report - cannot enter Sales category Box X

Path: Step-by-Step view, Investment Income, Stocks, Sales entry

The screen for proceeds and cost basis requests a Sale Category with pull-down menu.  The pull-down menu does not include "Box X".  The software then shows this as a error if a selection is not made and arbitrarily assigns the Sale Category as Box C (on the summary screen) if no selection is made.

The Form view, however, handles this correctly, and offers "Box X" in the pull-down menu.  However, Turbotax does not display this correctly if one then goes back to the Step-by-step view and edits the entry.
