Macs running El Capitan are having issues installing 2017 Turbotax Deluxe CD. Should I upgrade to OSx Sierra or High Sierra? Which OSx should I upgrade to?

TurboTax Premier 2017 does not work on my MacBook (running macOS Sierra 10.12.6). When I try to import 1099-DIV from my brokerage, I can see my brokerage is in the list but it does not allow me to choose it. It does not have any response after I click on my brokerage from the list. Does any one have this issue?
