It is too late to efile 2023 pr prior. Efiling closed on Oct 15, 2024. You have to print and mail 2023 now.
Be sure to attach copies of your W2s and any 1099s that have withholding on them. You have to mail federal and state in separate envelopes because they go to different places. Get a tracking number from the post office when you mail them for proof of filing.
Then when you file for 2024 you need to enter 0 for the 2023 AGI since you are filing 2023 late.
