The Home Office Deduction is available for individual taxpayers only and is not reported on a business return.
As a partner in a partnership, you may be able to claim a Home Office Deduction as Unreimbursed Partnership Expenses (UPE). If you were required to pay these expenses under the partnership agreement, you may report your expenses on Schedule E (Partnership Income). In this case, TurboTax will ask you about UPE, with follow-up entry at the end of the Schedule K-1 input.
See instructions for Form 1040, Schedule E for more info from the IRS.
