No, for real estate it does not need to be split. Are you entering 100% of the cost and price? Or are you manually splitting things?
If you are entering 100%, then you may be misreading the "Nonqualified Use" page where it asks you for the number of days of ownership and the number of days of "Nonqualified Use". In your case, because the rental was AFTER it was your main home, there is NOT any Nonqualified Use.
