Unless they updated the program (I think they have) if you enter zero days rented, the program will "force" you to delete the SCH E. If that happens, you'll get a pop-up warning before it actually deletes it. Just cancel out of the warning and enter 1 day rented. The fact you have zero income for that one day will be fine.
Assuming you did not live in the property for one single day during the year as your primary residence, 2nd home, vacation home or any other "personal" type of use, you still enter zero for personal use days. ANything else, and it will change your depreciation and reduce the amount of other deductions you are allowed to claim.
