No you didn't install Home&Business before. You need Turbo Tax Business program. It is a separate program from Home&Business. H&B is for personal 1040 returns that need schedule C for self employment. You bought the wrong program. Ask for a refund.
You can buy the stand alone do it yourself Business CD/Download program for Windows here (it is not available to do online or for Mac). There are 2 ways to buy it. If you want a CD you need to pick the Advantage Plan in the right box.
