Typically, a Health Reimbursement Arrangement (HRA) is funded by your employer and the amount your employer contributes to the plan is not taxable to you. Also, qualifying heath care costs that the plan pays for are not taxable to you.
You mention that there is money being taken from your pay for a medical plan by your union. This might be something else, but typically money taken from your pay for medical insurance would not result in taxable income but would be deductible as medical expenses. However, it would only benefit you if you were able to itemized your deductions, and then only to the extent your medical expenses exceed 7.5% of your adjusted gross income.
You may be referring to a Health Savings Account (HSA) in which case the contributions you made outside of you employer may be deductible. You would enter those in the Medical section of TurboTax where you enter your Deductions and Credits. Choose the 1099-SA, HSA and MSA option.
If you could clarify where you are seeing the payments reported, on what tax form, we may be able to help you better.
