E-file an Amended Return

Hello, I used the "amend a return" feature in TT2023 to amend my filing for this year which I filed back in February.  When done it let me print a PDF of the amended returns but didn't offer to e-file them.  Do I have to mail them in per the instructions or is there a way to e-file them?  I saw the e-file option in the file menu but didn't want to screw up my tax filings by trying it without asking about it first.
