I filed my taxes for 2016 through turbo tax but I cant find it now. How do I find it? My account it only shows 2017 filing but I didn't file my 2017 taxes with turbo tax.

I only see 2017 tax documents on my account. I have the receipt number from turbo tax from when I filed it back in January of 2017. But I cannot find it on turbo tax account.
