I need to amend my 2020 tax return. I have a mac and the 2020 version of turbotax is not compatible. Is there a mac compatible system?

You need to download the Mac version.   Ask support for the Mac download.  You can still open the same .tax2020 file in it.

Did you use the online version for 2020?  It should have given you a link to download the Mac version to amend.  See

Under Online it says.....

• If you would like to amend your 2020 return using the TurboTax Amend CD/Download software, select the link for your operating system (Windows or Mac) to download the software. (You'll also need to download the .tax file for your 2020 return, which you can do from Your tax returns & documents)
