We meet the requirements for TurboTax Free. Spouse + Me, T4s and spouse has RRSP. No Medical, No Charity being claimed. TurboTax tells me to pay for "Deluxe." Why?

This should be simple as I have three papers I am entering: 1 for me (T4), and 2 for Spouse (T4/RRSP). I have answered NO to all other questions. I get the message "TurboTax Free is for simple tax returns only. Based on what you told us, it doesn't include the forms you need".  The specifications for Free show that it can handle Employment income and RRSP contributions.
