You could perhaps code the vendor to your name / owner pay or the name of your HSA and code the category as a reimbursement since you are using your HSA to reimburse medical expenses on an regular basis. Otherwise there is healthcare premiums for your medical insurance and there is HSA contribution category. This category is under payroll option. You can code vendor names for each employee for their reimbursements. If it is for owner, code the relevant vendor.
