After you file

I have owned 2 rental properties in Indiana since 2013 but live in California.  I have never filed an IN state return, but realized this year maybe I should have.  The first year I had income from the rentals was 2015 of $6,037.  I also own 1 rental property in CA.  All the property income/loss have been combined on my CA state return up to this point. Do I need to amend my CA return deducting the IN properties and then file an IN non-resident return for these past years? Also where on turbo tax do you indicate these different State incomes?
