Are you saying that you efiled both returns and have received your Federal tax refund, but not an Ohio state refund that you were expecting?
First, be sure the state return was successfully filed and accepted.
Log into your Online TurboTax account. At the Tax Home what is showing for the "return status" of the state return? If you don't see any "status" on the main Tax Home page, then scroll down and click on "Your Tax Returns & Documents", expand that section and choose tax year 2018, then look for the status.
If that confirms the efiled state return was "accepted", then here's how to check on the Ohio state refund:

I just found a previous thread of yours. Are you not a USA citizen? i.e., Are you a non-resident alien for tax purposes? If so, did you file the correct Federal form; i.e., a Form 1040NR? TurboTax cannot prepare Form 1040NR.
