I'm strictly using 2017 Turbo Tax (TT) for Home & Business to check my CPA and to learn TT for preparing 2018 taxes. Should I do anything differently using TT this year?

I had to change Tax Preparers this year because last year's Tax Preparer retired, but I thought at the same time I would learn how to use Turbo Tax this year to check my new CPA that I just hired and to possible use Turbo Tax next year. So my question is, since I'm only using 2017 Turbo Tax to check the performance of my new CPA and for learning Turbo Tax software for maybe use next year, should I do anything differently when using Turbo Tax this year?
