Tax Year 2015: How do I answer TT question "How did you enter home office expenses in 2015" ?

I did NOT have a home office in 2015, but did have one for 2016 that I'm now trying to claim the deduction for. How do I answer this TT interview question: "How did you enter home office expenses in 2015" ? The ONLY two answers shown on the TT interview screen are : a)I entered actual expenses OR b)I took the simplified deduction.
