In Turbotax Business (used for a partnership), how do I account for a 1099-S received for monies paid for a pipeline easement?

Depends on if the whole property is affected or just part. If the whole property is affected reduce the basis....if only a part is affected the gain is the difference between the payment the partnership got and the basis of the part of the property affected.

To enter your 1099-S into TurboTax, follow these instructions:

1. While in your TurboTax account,
2. Select Search from the top right side of your screen,
3. Enter 1099-S,
4. Select Jump to 1099-S,
5. Follow the on-screen prompts to complete this section.

there's no link to a 1099S....entering 1099S in the box is useless.

When you enter "1099-S" in the search box, you should see a "jump to" option that will bring up this screen:

Thanks everyone!  I appreciate the help!
