Extension question for State Return

I own several MLPs that issue K-1s and K-3s.   Since the K-3 doesn't come until late summer, I always file an extension for both state and federal taxes.  I create the extension through TurboTax and mail them in.

 

I just finished up my taxes, and I found something during my final review.   On my NC State tax form, there is a question "Were you granted an automatic extension to file your 2023 Federal income tax return, e.g., Form 1040?".

 

The box is checked "No".   I would have expected it to say "Yes", since I printed and mailed in both Federal and State exension forms before April 15.    I can over-ride this value and change to Yes.

 

Is the form I submitted prior to April 15 considered an automatic extension, or just an extension.  How should this box be checked if I mailed in an extension?
