Why will Turbo Tax not let me E-File 22 returns when the file date was extended to Feb 15th 2023???

Actually you can not efile a 2022 return from Turbo Tax.   If you need to prepare one you need to use the Desktop program.

If you want to file for free you can fill out the forms by hand. Here are some basic forms…..

Here is the IRS 2022 Form 1040

or if you want bigger type use 1040SR for Seniors,
https://www.irs.gov/pub/irs-prior/f1040s--2022.pdf

And 2022 Instructions

Sch 1 : https://www.irs.gov/pub/irs-prior/f1040s1--2022.pdf
Sch 2 : https://www.irs.gov/pub/irs-prior/f1040s2--2022.pdf
Sch 3 : https://www.irs.gov/pub/irs-prior/f1040s3--2022.pdf

Then when you do file 2023 enter 0 for the 2022 AGI since you are filing 2022 late.

You have to print and mail prior year returns. When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return. Don’t forget state.

Important! Mail Federal and State in separate envelopes and mail each year in separate envelopes.
