Provided for you is a TurboTax FAQ that includes the OS system requirements for MAC.
Unfortunately, there is no way to install the Mac software for you. You could use TurboTax online, or you could consider installing a virtual Windows system on your Mac and using the Windows version of TurboTax. The cost of this would probably make the operation unattractive unless you have other reasons to run windows programs on your Mac.
Re: Have used TurboTax since it was MacInTax I'm not able to upgrade the system on my Mac. I am still using macOS Catalina Is there anyway I can continue to use TurboTax?
@Peter913 - minimum system requirments for the ONLINE version....you could use that.
Mac OS X 10.15.x (Catalina)
@Peter913 If you can't install Turbo Tax Desktop program you can transfer from your 2021 return from your computer into the online version. You need to have the file ending in.tax2021 on your computer.
If you used the Desktop program last year here’s How to transfer into the Online version, expand the blue link if you used the CD/download last year
If you used the Desktop program before you may notice several differences and not like the online version. It has less features and no Forms Mode. You can only do 1 return. Federal and state are separate fees.
Your return is only saved online so be sure to save both the .tax2022 data file and the pdf file to your computer when you are done. In case you need to amend in the future or if you need a copy to get a loan or something. You might not be able to access your online return when you need a copy.
To use the Online version you would have to start over in a new online return and pay for Online separate from the Desktop program. Then try to get a refund for the Desktop program.
