In turbotax guided home office deduction (web interface), it asked me about when this space started to be used as an office, for example from July 2020. However this guide also asked me about the TOTAL rent expense of my whole house, and the TOTAL utilities expense of the whole house, insurance, etc. I assumed it is asking me for the whole year (I read so!). Must I enter just those amounts from July till December or for the whole year (12 months)? One expect that Turbotax will do the math, however It seems like turbotax is not computing just from July if I entered the 12 months expenses.
