Does anybody know where do i file the expense for taking care of my senior mother as a disability tax credit

To claim the disability tax credit from a dependant You will first need to have filed a T2201 with the CRA. You will claim it as the link below shows, in TurboTax Online or in TurboTax Desktop.

 How do I claim the Disability Tax Credit transferred from my dependant? 

Thank you for choosing TurboTax.
