I lived in CA through Oct and moved to OH for the last few months of 2018. I won money at a casino in Ohio. Would I need to claim the winnings on both state tax returns?

Were you still a resident of CA when you won? If so, you owe both states. If not, you owe only OH.

I won one jackpot while still living in CA but was in OH finding a home and another jackpot after I moved to OH.

The first jackpot should be filed with both CA and OH; the second with OH only. If you can determine how much of your OH tax is due to your first jackpot, you should be able to claim a credit for that part of the tax on your CA tax return. Not so for the second jackpot, since by then you were a resident of OH and not CA. If it's too complicated for you to figure out with TurboTax alone, consider TurboTax Live or a local tax professional.
