Self employed and paid WSIB premium. Where do I enter it on the T2125? Also where do I enter CAA Membership and 407ETR Toll charges on the T2125?

While in the Self-Employed section of TurboTax, on the T2125 Statement of Business Activities, claim your WSIB Premiums as "Insurance."

You can claim under expenses when filling out T2125. Use the T2125 form to report either business or professional income and expenses. This form combines the two previous forms, T2124, Statement of Business Activities, and T2032, Statement of Professional Activities.
