If you want to use a TurboTax Online product, you will need TurboTax Premier Online Edition to report the S-Corp K-1 on your return. If in addition to the K-1, you are reporting income from self-employment, you will need to use TurboTax Self-Employed Online Edition.
If you prefer to use the CD/Download product, TurboTax Home & Business will work for you.
