The current online software is only for 2022 returns. You could do a "dummy" 2022 return if you want to, but just do not try to file (or pay). If you want to prepare returns for past years, you would need to purchase the CD/download and use it on a full PC or Mac. Each year has its own software. You can get software for 2019, 2020, 2021 or 2022.
