Cannot efile an amended return

[RES731]

I have Turbo Tax Desktop premier and need to amend my 2023 return for a missing 1099.  I efiled my federal last year and used my States website for state taxes.  When I enter the amended return it says I cannot efile due to state not supporting efile.  However, I never efiled the state using TT.   

I tried removing the State return, but then TT says the efile period is over and it wont allow efile a federal amended return.

How can I  efile the amended Federal return for 2023?

You can't.   E-filing is permanently closed for 2023 returns.  The only way to file it is by mail.   Print it, sign and date it in ink, and mail it in.
