You can't transfer tuition credits which were carried over. You can only transfer tuition which weren't use to bring down your tax to zero. TurboTax calculates this amount for you.

Hi Brenda, I wasn't asking about transferring credits.  I was asking about using credits carried over.  Turbo Tax does not calculate the correct amount of credits to use to reduce the taxable income to zero.  It uses all the carryforward credits instead.

The program needs a software fix.

The oldest tuition credits will always be used first and the newest unused credits will be added to the carry-forward amounts which the Canada Revenue Agency(CRA) will continue to automatically use towards your income as needed in the future years till there is no more carry-forward amount left.

Thank you for choosing TurboTax.
