No, the IRS instructions state that self-employed partners can take the deduction as an unreimbursed business expense if the specific areas within their homes meet the eligibility and exclusivity tests. Other tax software we use readily accepts and prepares this information, so i was hoping an option existed in ProSeries. Apparently it doesn't. Wouldn't be the first time.
(edit) Should also mention that these partners likely had no office or other place of business to report to for the majority of the year due to COVID-related office closures, and thus conducted business solely/primarily at home.
