First if you are new to a partnership and filing a partnership return then I highly recommend you seek local professional assistance to get educated on the workings of partnership returns and the keeping of the books for the same. And if this is for the 2018 calendar year form 1065 be aware the return is now every late and the penalties and interest is accruing monthly.
Next ... those expenses would only be on the partnership return IF the partnership reimbursed the partner for the amount ... then they would be deducted as the kind of expense that was reimbursed for example if it was for office supplies it goes under office supplies. If the partnership did not pay back the partner then it goes on the partner's personal tax return as described in the other answer BUT only if the partner was required to incur those expenses per the written partnership agreement. Seek professional help if any of this sounds foreign.
