If you are self-employed and have created an LLC, you file your business income and expenses on Schedule C - unless you elected to be taxed as an S-Corp. If you are using Schedule C, you would include your travel expenses as business expenses on Schedule C. There is no need to treat it as a reimbursement. If you have chosen to be taxed as an S-Corp, then you would want to report the expense as business expense on your Form 1120-S.
