Was my 2019 federal tax return e-filed?

I had to paper file my Illinois state tax return because I did not have my 2018 AGI available, but I believe my federal tax return was filed electronically. When I log into TurboTax, there's a message that says, "Your 2019 federal tax return was e-filed on" but there is no date. The date should be January 31, 2020. I also continue to receive email reminders from TurboTax that my "2019 tax return was not e-filed," but is this referring only to the state return (which I had to do on paper), or also my federal tax return?
