PA-8453: still the same protocol?

So I've run into the same situation (and confusion) as other members: Before I submitted my PA tax return electronically, I was instructed by TurboTax to "Sign and date Form PA-8453 within 1 day of acceptance."  Reading the previous comments from two years ago, it sounds like I do NOT need to sign/send in the form, but rather just sign a copy and keep for my own records.  Does this still hold true for the 2023 tax year, or have things changed?  I would appreciate any insight, thank you!
