Am I able to amend 2023 return with this version of TurboTax?

The online versions are only for 2023.  Do you need to amend the 2022 return you filed in 2023?  

You should not amend until the first return has fully processed and you get the first refund or your tax due payment has cleared.

2. On the home screen, scroll down to Your tax returns & documents and select the year you want to amend.
3. Select Amend (change) return, then Amend using TurboTax Online.
4. Carefully follow the directions to start your amendment.
5. Your refund will go to zero, don't worry, that's normal.
6. On the screen OK, let's get a kickstart on your amended return, select the reason(s) you're amending and Continue.
7. When you reach Here's the info for your amended federal return, select Start next to the info you need to change.
8. Continue through the screens, make the changes you need to make, and carefully answer the remaining questions to finish amending your return.
