I live in Ontario but have a Quebec pension with taxes deducted where do I enter these amounts please ˋ

Because all you need to do is capture and report the QC tax paid, here's what you will do: 

First, use the option for "l worked in QC" 

 

2nd: create a new T4 for with box 10 set to QC and enter the amount paid on the RL-2 as tax paid in the box E appearing at the bottom on the T4 with nothing else on the T4. Hence, nothing is reported as a T4 to CRA:

By doing this, the QC tax will be reported and the rest of the entries are accurate. 

Thank you for choosing TurboTax.
