If you are filing an amended return for 2022 or earlier you CANNOT do so thru the TT efile system ... all prior year returns must be mailed. Only some professional tax pros using professional tax programs can efile prior year returns. And the 2023 returns have not started processing yet (expected to start 1/29 although the IRS does pull some early for testing purposes) and amended 2023 returns will not be allowed until the end of February at best.
