There is no entry field for you to input box 134 on TurboTax, as it is not necessary for you to declare.
Box 134 is the amount that the T5013 has calculated as the Dividend tax credit based on the Box 133 Dividend amounts. TurboTax automatically includes this amount based on your T5013 plus any other relevant amounts in your return to calculate the Dividend tax credit shown on Schedule 1 Line 425.
Thank you for choosing TurboTax.
