The only thing you could do with the online version would be to make a new test account with a different username and password ( it can be linked to the same email address) and use that test account to play around with the numbers. You would be looking at 2022 tax calculations, but so far there are no significant differences for 2023. Since the online version only requires you to pay when you are ready to file, and you won’t be planning to file this test, tax return, it won’t cost you anything to play around. Just be sure that you don’t accidentally file it, and that you don’t use it as your starting position for your 2023 tax return.
In general, the desktop program is much more flexible regarding multiple tax scenarios, tax planning, and so on. However, if you have already filed your 2022 return, it won’t make much sense to buy another copy of 2022 just for practice purposes.
