Why am I being Required to buy Premier? I have nothing but a T4, RRSPs and a spouse with no income?

I don't know how much simpler it gets.  I am trying to file for myself and spouse.  Spouse has no income.  I have a single T4 and RRSPs.  Turbotax saying the free version doesn't include the forms I need, must buy Premier.   It worked last year.  I double checked I don't have anything answered incorrectly.
