You will not find entry fields for these two boxes as it is not necessary to enter T5013 Boxes 132 and 134 in TurboTax.
-Box 132 is the actual amount of dividends which is grossed up to  Box 133 amounts which is the amount that is entered and used in the TurboTax calculation.
-Box 134 is the amount that the T5013 has calculated as the Dividend tax credit 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.

If only the actual amount of dividends are being shown on the T5013 box 132 then please gross them up to  the taxable for  Box 133 amount by multiplying by 1.38 if its eligible dividends, 1.17 if its ineligible dividends.
