How to confirm if Form 568 was e-filed

[Wannabe]

I am first time user of Turbo tax Home and business (Mac). I filed for Federal personal extension before 7/15 and then e-filed the actual Federal and State return last week.

When going through the forms from Turbo tax, there was a note that I should mail in Form 568 along with the voucher and LLC fee for my single member LLC. How can I confirm if Form 568 was e-filed for me by Turbotax? I saw a response on one of the forums here that the 2019 version of turbotax supports e-filing Form 568.

If you personally followed the instructions and printed/mailed the form, that confirms it was filed. If you did not personally print and mail the form, that confirms you did not file it.

Ok, you are saying that I should trust the note to mail Form 568, ok. If there is really a new feature in Turbotax 2019 to e-file Form 568, why did it not do that with my personal returns?
