The link provided doesn't really answer your question. What you enter is the amount of your total income that was generated by any business you have an ownership interest in, that is registered in HI and/or has a physical presence in HI. So for the rental property you own in HI, you'll enter the gross amount of all rents received. This will include any late fees as well as any other income received from any source for any reason, for that rental property.
