How do I upgrade to Small Business?

[buck700]

I would like to upgrade to Small Business for 2015 and 2016 returns. How do I do that?

For 2016, you are already asking from TT Self-Employed.

For 2015, you must purchase the 2015 desktop software. Any version will do.

However, if you have a C Corp, S Corp, or Partnership, you need to purchase 2015 Business and 2016 Business.

Please clarify your situation.
