Investors & landlords

As you state you are using a Desktop version of TurboTax, switch to the Forms view and look at the entries in Form 8949 to see if there are duplicated transaction perhaps from an inadvertent second import.  If so, you can delete them or, as there may well be many, try deleting the form and reimport to see if that fixes the problem.  Good Luck!
