TurboTax 2023 desktop refuses to e-file amended tax return? ("closed for the season")

I just went through the steps in TurboTax 2023 to amend my 2023 return.  It then told me to print out the 1040-X and mail it in, but also told me if I click the File tab, it might e-file it.  When I click the File tab, it says E-Filing is closed for the season since 10/15/2024.  And yet, the IRS says it accepts e-file of amended returns for something like the past 2 or 3 years.

 

Am I hitting the wrong buttons in TurboTax 2023 to get the 1040-X to e-file, or does TurboTax really stop e-filing amended returns after October of the following year?  That seems very restrictive.
