sold my business in 2016

Well all 2016 returns must be paper filed and you have to use the correct 2016 downloaded program ... you did not say what kind of business you had ...

If it was filed on a Sch C as a sole proprietor that goes on the personal return ... if you have already filed the return then you will need to amend it ... you can use Deluxe to save a couple of bucks ...    https://turbotax.intuit.com/personal-taxes/past-years-products/2016/

If it was a partnership or incorporated you need the Business version ... Home & Business will NOT work ...
