I have a file in Indiana, but I underage took money out from an Ohio Retirement Fund. It wont let me add this to my Indiana form,but I cant find where to add in Ohio form

You don't add it to your state return.   All retirement distributions (1099-R) get entered on the federal return and TurboTax will transfer that info to your state return(s).

Where do I enter a 1099-R?   You should have already received this form.
