The K-1 needs to be reported on your federal return. If you have already filed your taxes, you can file an amendment to add the K-1. If you have not filed your personal tax return, just include the K-1 when you file.
Where
do I enter a K-1 that I received?
You probably only need to include it with your Kentucky return, but you may need to file an Indiana return too, but TurboTax will handle that. It depends on your residency during 2018 and your income. Just enter the K-1 on the federal and it will flow to the state(s) returns. Use this
link for the amending instructions, and you will need to use TurboTax Premier to enter the K-1 if you are using the Online program. If you are using the Desktop programs, all versions will allow the K-1 entry.
