Thanks, but I fixed my return with CRA help.  Wouldn't have been caught by CRA either as Turbotax boosted my income and missed an associated deduction.  Should be fixed, so others don't lose out.

Can you clarify what you mean that it missed an associated deduction?

The TurboTax error is in the HBP.  It incorrectly would not let me include my required 2023 HBP repayment, thus increasing my income and my taxes.

We will look into this. Thank you for your feedback.
