" How do I go about reporting the reimbursements received by my job since it’s not reported on my W2".
You need to verify that's what happened. As previously explained that's not how it usually happens.
However, if your employer treats your education as a business expense (job training), instead of tuition reimbursement, the entire amount can be tax free (not included on your W-2). In that case, you may only count $14,028 - 10,020 = $4008 for the LLC.
