The TurboTax Premier desktop edition supports entry of a Schedule K-1 that you would have received from the S-Corp.
To enter a Schedule K-1
Click on Federal Taxes (Personal using Home and Business) Click on Wages and Income (Personal Income using Home and Business) Click on I'll choose what I work on (if shown) Scroll down to Business Items (Business Investment and Estate/Trust Income using Home and Business) On Schedule K-1, Q, click on the start or update button
Or enter k-1 in the Search box located in the upper right of the program screen. Click on Jump to k-1
@kerihoz I think you can enter self employment income into the Online Deluxe version (and Premium). But if you need to enter expenses you need Online Premium or any of the Desktop programs. All the Desktop programs have the same forms.
