It says my taxes were filed, but I’m not sure it was e filed? I don’t want to n mail it in. I don’t have a printer.

Go to the home page where it shows how much you are getting back, and at the bottom, select “e-file details” and it should drop down showing you when it was filed and when it was accepted. 

You can check your e-file status by following the steps in the below TurboTax FAQ:
