Question marked as
The model year of a MacBook Pro is available at Apple menu > About This Mac.
A mid-2010 through late-2011 MacBook Pro can be upgraded to High Sierra 10.13.6 but no later version.
A mid-2012 through early-2013 MacBook Pro can be upgraded to Catalina 10.15.7. See: https://support.apple.com/en-us/HT211683
A late-2013 or later can be upgraded to the current version of Big Sur. See: https://support.apple.com/en-us/HT201475
If your MacBook Pro is a late-2011 or earlier and cannot be upgraded beyond 10.13.6, be aware that TurboTax Online is a good option and can be used for much older versions. See: https://turbotax.intuit.com/personal-taxes/online/system-requirements
