Well for the 2019 S-corp you need TT Business and for the 2019 personal return one of the personal programs ... use the deluxe version.
Then you only need a personal version for the 2020 tax year ...
i strongly advise you to use a tax pro for the s-corp return. we can not see the sales agreement and that could have a substantial effect on what we would advise and where to report it (could be on S corp return if assets sold or it could be schedule D of your return if stock sold). the return is late. The penalties for late filing are about $200 per month per shareholder for every month late with a max of 12 months.
The professional should also be able to address and possibly reduce the late filing penalty and educate you on the taxability of the future payments including the interest you should be charging on the loan.
