What is proper way to claim expenses required for employment (ie. Medical License and Insurance)?

You would put your amount either the GST, the HST or exempt/zero rated column depending on what tax you paid.

To enter professional fees in TurboTax Online, click the Find tool (🔍) and search for “union” in the top box. Click “Union or Professional Dues” in the bottom box to select it, and then click the Go button.

If they were related to your employment, eligible union dues or professional fees include: 
 

• annual dues for membership in a trade union or an association of public servants
• professional board dues required under provincial or territorial law
• professional or malpractice liability insurance premiums or professional membership dues required to keep a professional status recognized by law
• parity or advisory committee (or similar body) dues required under provincial or territorial law

Annual membership dues do not include initiation fees, licences, special assessments, or charges for anything other than the organization's ordinary operating costs. You cannot claim charges for pension plans as membership dues, even if your receipts show them as dues. For more information, see interpretation bulletins IT-103, Dues paid to a union or to a parity or advisory committee, and IT-158, Employees' professional membership dues.
