My experience with a trust and TurboTax Business goes up to the 2021 tax year, and up to that point there was no option to import documents as is done in the personal versions. Check the "File" drop down menu to see if an "Import" item exists there now as in the personal desktop versions. From what you've said, I suspect this feature is not yet available.
This issue was an irritation for several years when I had to do trust returns. Given that the Business versions are more expensive, it's a major lack of functionality.
