How do I find out on turbo tax whether I have already e-filed?

[betsy1]

I thought I e-filed both state and federal returns about 12 days ago. Today when I reviewed the filing for purposes of amending the returns my turbo tax says "It doesn't appear that you have refiled". 

Can I count on turbo tax's response? I don't want to amend a return that was never filed.

You can check your e-file status by using the source provided for you below. It will let you know if have completed your filing or not.
