Win 11 upgrade -- NOt

Worked with Microsoft help desk  for two hours and could not upgrade my computer  from win 10 to Win 11.  Didn't offer security upgrade.  Now after using  turbo tax  for the last  15 years,  I have to buy a new computer in order to stay a turbo tax customer.  Will turbo tax  home and business 2025  run with Win 10  security  extension  subscription  or  another customer  goes to the competition?
