The partnership return is filed by the partnership or the owners/responsible person. That appears to be you. The IRS will know who is getting distributions based on the 1065 and your 1040s. These are pretty basic questions, so I think if you are experiencing some confusion you should hire a qualified CPA (hire now before things get too busy during filing season).

Mr. Zelinger's answer is right on point. Just as a point of clarification, the Form 1065 issues a K-1 to you and your partner, which is also filed with the Form 1065 filed with the IRS. It will reflect your percentage ownership. This means you cannot own more that 99.9% if you wish to be a partnership.
You do not file the K-1 with your Form 1040. You report the net income on Sch E of your Form 1040, and if there are other items, such as interest paid, or charitable deductions made, these items are reflected on other lines or schedules of your Form 1040. Speak with a CPA or Enrolled Agent.
It is also noted that while your partner did not make a capital contribution in the form of cash to the business, I assume he did something of value, and that you may, after consulting your attorney, decide to place a value ("sweat equity if you will), on any effort he contributed, but that is for you and your partner to decide, and then reflect any such value as a capital contribution and reflect it in the minutes of the LLC.
If you do not have an Operating Agreement, you should secure one from your attorney, and if you do not have one, I would be happy to be of assistance. I can be reached at 973-994-9080.
Good luck with your venture.
