Sorry, TurboCSV doesn’t provide any import capability for the post ID. WordPress doesn’t have any way to assign it either, since the database normally assigns it automatically.
This might work though:
1. Create dummy (empty) posts for all of your IDs directly in the database. For example, just populate the wp_posts table with the ID number only. I think they’ll show up in WP as empty posts.
2. Then do an ‘update’ import from TurboCSV with your actual data (you can update by post ID, just not create)
