I checked the imported T5008 items, and they did not have the "Type of Income" field nor the Disposition Date field populated.
Once updated, they showed up on the Schedule 3 Supp T5008 as expected.
TurboTax review also flagged the blank entries as an error "In order to report income from your T5008 slips properly, you must indicate the type of income for each slip."
Thank you for the reply.
