Solved
I filed in 2014 with turbotax cd software but can't find my copy and Ohio state department of taxation says I didn't file.
If you used CD or download software (rather than inline), Intuit will not have copies of your returns. They are stored on your computer. Open the 2014 program and review the forms.
If you deleted the software, and have a PC; go to my documents. There should be a TurboTax Folder. A PDF copy of your return may be there.
