F4562 and IRS form 4562 are two physically different forms.
"do I need to enter 2017's "
Not sure in what context you're asking this. Since you started renting out the property in 2016 and 2018 is your first year with TTX, you must work this through the assets/depreciation section. To enter the data correctly you need the 2017 IRS Form 4562 titled "Depreciation & Amortization Report". You may or may not also need the one titled "Alternative Minimum Tax Depreciation".
When working this through the program you will be asked for prior year's depreciation (or depreciation already taken) It's important to enter the correct amount, and folks in your specific situation enter the wrong amount 99% of the time. To get the correct amount, take a look at the 2017 4562 and add together the amounts in the prior depreciation column and current depreciation column.
You will enter that total in the TTX program when asked for prior depreciation already taken.
Now for the HI state return, the data from the federal return is imported to the state and dealt with mathematically as necessary. But you "still" have to work it through the state program, even if you don't change anything on any of the screens.
Then when you print the state return, the HI form F4562 will be generated with that, if it's necessary to file that form with the state. (it may not be if there's no changes to your assets from the 2017 form F4562)
Not that it applies directly to you your specific situation, but I've added some important info in the answer box below for your reference. When dealing with rental property, I can't stress the importance of absolute perfection in the first year of renting, or in the first year of using TurboTax. Even the tiniest of mistakes will get exponentially larger over time. Then with you catch (if the IRS doesn't catch it first) the cost of fixing it years down the road *will* be expensive. so when it comes to the numbers, perfection for you is not an option....it's a must.
