Soft Credit type not initially available for selection on donation import

The Soft Credit Types default to 'In Honor of' when they are uploaded.

The option group doesn't actually appear when you first start the import with a saved field mapping.

Workflow -
Complete upload files page of contribution import.
Select a saved field mapping.

On match fields page, field that has been chosen for soft credit (used email address for this example) displays Soft Credit option and Email option in the matching CiviCRM fields column.

Select another option from either of the dropdown lists.

This will then display the Soft Credit Type option group.
