I submit that the "IF PROPERLY DEDUCTED" is probably misapplied here. This statement is in a section talking about ratios, i.e. "reasonable allocation," and could possibly be interpreted as indicated, but that seems a stretch. There are explicit statements later about limiting the deduction based on sections 67 and 68 (both moot this year). There should be a comparable clearer statement about itemization vs. standard deduction.
