In the “Find” icon at the top right of your screen, type in “Tax transfer for Resident of Quebec”

Once this amount has been applied federally, the portion automatically transfers to line 454 on your TP1. This will be reflective of your province entry in your T4.

It still does not work...

the amount I want to transfer to the quebec Government  on line 43800 (T1)  corresponds to 26% of the amount of income tax deducted on line 43700 of my T1... and the system still does not let me transfer it

I have done my spouse declaration and it worked for her.... for me, I cannot transfer any amount, I have tried with several amounts and the only one that works is zero... any solution Intuit?

I have attempted to duplicate your issue and my amounts transferred correctly, therefore I will ask you to contact us by phone or private message on our Facebook and Twitter social networks with a screenshot of the error so can we assist you further. 

I hope this was helpful
