The deadline to use online TurboTax software was October 15, 2024. It is now too late to use online. If you still need to prepare or finish preparing a 2023 (or earlier tax year) return, you have to switch to the CD/download on a full PC or Mac. And you will have to file by mail; e-filing is now closed.
CD/DOWNLOAD (This requires a full PC or Mac—-cannot be used on a mobile device)
