Im not sure if you have filed my 2018 tax return?

[TurboTaxKim · Accepted solution]

If your return was successfully NetFiled, you should have received a NetFile Confirmation Number upon NetFiling, as well as an email saying it was successful. 

If you did not receive this number, you'll need to open up your TurboTax return and complete the steps to NetFile again. 

Here's some more information on finding your NetFile Confirmation Number and NetFiling your tax return:
