I did not file in 2015 with TurboTax bc of a special tax situation. TurboTax is including 2015 info on my tax return that is incorrect. How do I amend this 2015 info?

I started my 2015 taxes with TurboTax but never finished them. Instead I filed with an accountant. I believe TurboTax is pulling numbers from this old, partially-completed return.
