You have the years mixed up. The current program is 2023 for 2023 returns. So you would want to use 2023 to do a mock 2024 return. Next year in 2025 you can buy the 2024 program (actually it should go on sale in November 2024).
If you want to buy 2023 now to test.......You can buy the stand alone do it yourself Business CD/Download program for Windows here (it is not available to do online or for Mac). There are 2 ways to buy it. If you want a CD you need to pick the Advantage Plan in the right box.
