Permanent easements are treated as a property sale. If this is your personal property, report the sale in the TurboTax section Income>>Investment Income>>Stocks, Bonds, Mutual Funds, Other. Answer that you did not get a 1099-B, and then follow the TurboTax instructions carefully. If it is business property, you report it as the sale (disposition) of a portion of that business asset (Land).
In both cases, your "cost basis" is the cost of that portion of the land that is subject to the easement. You will likely need to calculate this based on the total cost of the parcel land and the percentage of the total parcel that is subject to the easement. You must then reduce the cost basis of the land you still own. See the section of IRS Publication 551 at this link for more information.
Temporary easements are treated as rental or lease income in the Rentals section of TurboTax.
