Get your taxes done using TurboTax

Or make the decision to leave TurboTax and do your taxes with another company. I personally find this requirement to upgrade every time a new OS comes out  onerous. If you upgrade very time a new OS comes out, then you are set...until your Mac can't do the upgrade..then it's new Mac time. I keep my machines a long time, and if the new OS doesn't have big improvements, I may just skip upgrading.
