@wnetmw I am so sorry. I stand corrected! I've looked back at former years' returns and see exactly what you're saying.
So the proof of your timely filing of NJ return would be only the email you received from TurboTax. As for the date you scheduled direct debit from your account, I have no idea how you'd prove that. I certainly agree that TurboTax should include dates scheduled for both federal and state direct debits.
As the Electronic Postmark applies only to the federal return, that's no help either.
EDITED TO ADD: See @DoninGA 's response earlier in this thread to see the date of your e-filed state return as well as the accepted status once the return is accepted.
Hopefully, you have saved screenshots or emails proving when you e-filed your returns. You should be able to see the status of your state return on the state's website.
Sorry I can't be of more help.
