The last I saw on a TurboTax webpage a couple of days ago was import of CSV was temporarily unavailable. I could not find where I could indicate to be informed when available. In Desktop Deluxe there is currently no option to import a CSV. There is a page that may be suggesting you need to upgrade to Premier to import. I not sure.

I could not find a way to import even a 1099-DA.
