TurboTax doesn't have remittance vouchers. You will have to access this through CRA, either through your My Account or here: https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/corporation-payments/make-a-payment/payment-vouchers.html#rc158. Alternatively, you can make your payment online through your bank and this doesn't require a remittance voucher (only your SIN to set-up your billing account).
