Extension Discrepancy 4868

Hi, I filed an extension before due date of apr 18 2022 for my 2021 taxes. However; on the irs form 4868, we see the following statement under late filing penalty:

 

Late Filing Penalty

"A late filing penalty is usually charged if your return is filed after the

due date (including extensions)."

 

Does this mean; if return is filed late AFTER my extension? Or does this mean, a late filing penality if your return is filed after the original due date april 18; regardless if an extension was filed?

 

Turbo Tax explicitly states that filing an extension does remove the late filing penalty fee of 5% per month but of course not the late payment fee. The IRS' rhetoric however; is colored and vague.

 

I interpret their wording to mean whether you file an extension or not, you owe late filing penalties.
