Where to enter tuition transfer from non-dependent child? System only allows for entering transfers from dependent children, but that is not always the case.

The CRA rules for Tuition Transfers only allow the transfer to be made to your spouse (or common-law partner), their parent or grandparent, or your own parent or grandparent. For this reason, you will need to enter the person who is transferring the amount as a "dependant" in TurboTax. 

The attached CRA Schedule 11 clearly states this rule, as does page 13 of the following CRA publication.

• Students & Income Tax: https://www.canada.ca/content/dam/cra-arc/formspubs/pub/p105/p105-01-20e.pdf
• Schedule 11:  https://www.canada.ca/content/dam/cra-arc/formspubs/pbg/5000-s11/5000-s11-19e.pdf

So we have to list them as a dependent, even if they are over 18 and not living with us? 

Here is how to correctly enter tuition transfer on TurboTax.
