Does this mean I can't expense the furniture?
Not necessarily, but you somehow managed to generate the wrong statement (the one you are referring to is for the QBI (Section 199A) deduction).
Regardless, in another thread you mentioned you were renting at a rate that is below fair market value. If that is, indeed, the case then each day you do so is considered a personal use day and no deductions are allowed as a result (other than Schedule A deductions such as mortgage interest and property taxes).
