Do you need to file 2023? Sorry it's too,late to start a 2023 or prior online return or use the mobile app, either on Turbo Tax or the IRS. And too late to efile 2023.
Don’t forget your state. And you will have to print and mail your returns. So 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.
