The correct way to do it would be to use different software that is capable of doing it correctly.
As a work-around, you could enter a mock rental property that shows the carryover, and say you disposed/sold that rental. But will incorrectly include a (mostly blank) Schedule E as a rental.
Another option is to enter it as a negative amount of "other income". But has potential problems and drawbacks as well.
But again, TurboTax is rather negligent for not being able to do things as it should be done, so you may consider other tax software that may be able to do it correctly.
