Depends what kind of business entity you have set up. Turbo Tax Business is for 1041 Estate/Trust Returns, 1065 Partnership/multi member LLC and 1120 S or C corp returns. It will not do your personal 1040 tax return.
If your business is a self employment/sole proprietor/independent contractor/freelance etc. or a Single Member LLC that is NOT a S corp. you file Schedule C in your personal tax return. Any Desktop version will work but the Home & Business version will have the most help. If you want to use the Online web version you would need to use the Self Employed version to fill out schedule C.
