Did I already file my taxes for 2016?

I tried filing my taxes earlier this week but, it told me that my forms weren't ready to finish filing. I came back today to finish up but it started all the way back at the beginning. That would be fine to do it over again but I already purchased TurboTax deluxe and it's asking me to purchase it once more to finish. I just need to know if my taxes have already been filed or not.
