You do need Premier (or Home & Business) to import K-1s into TurboTax Desktop or Online. Since Deluxe does not handle K-1s, you will have to manually enter (under Business Items) your K-1 and you must be using TurboTax Deluxe (or Basic) Desktop versions in order to manually enter a K-1.
You can, however, import your 1099-B statement for stock sales using Deluxe (Desktop or Online). Look under Wages and Income and import your brokerage statement by click start next to 'Investment Income'. You will be able to import if your institution is on the list.
