Can't amend previous year's return

I submitted my 2023 return with turbotax desktop. I need to amend it, so I open the 2023 desktop app and choose to amend and go through the steps. When everything is updated and I try to e-file, I get an error saying:

 

Your Transmission Didn't Go Through

TurboTax was unable to send your return to the Intuit Electronic Filing Center, for the following reason:

Transmission failed: the intuit filing electronic center is close for 2023 personal income tax filing season. October 31 2024 was the last day to file your returns electronically. 

 

I'm confused, because everywhere I read says you should be able to e-file the 2 previous tax years. Is there a way to e-file using turbotax? For example, it says NY state I have to e-file but the software won't let me.
