"....which when clicked on breaks into 3 folders ("32 bit", "forms," and "installer""
It actually sounds as if the program is already installed on your computer (see first screenshot and note the names of the folders in the Business 2018 directory).
If you can manage to get into Windows Explorer and expand Program Files (x86), you should see the TurboTax directory. If you expand that, you should see Business 2018 and expanding that should reveal the three folders you mentioned. Open the 32bit folder, click (double-click) on TurboTax.exe and the program should open (see second screenshot).
