Thank you for choosing TurboTax!

Hello, it should automatically split rental income if the appropriate fields are filled. Are you using TurboTax Online (TTO) or TurboTax Desktop (TTD)? In case you are using TTO, you can go to T776 Partner Details Statements and add the appropriate split amount. TTD should be similar.
