Can I file an amended tax return with TurboTax Online when I submitted it using Desktop? I no longer have access to the machine I used to file my taxes with Desktop.

I live in Kentucky but work in Ohio. I filed taxes for Ohio and Kentucky. After filing (and paying Ohio $1,700) I found out that I did not need to file for Ohio because OH and KY have a reciprocal agreement. Was told to file an amended return. I no longer have access to the machine I used TurboTax Desktop with. What do I do?
