Errors in TP-128 form CCA calculation in Turbotax Canada 2025

If you are using TurboTax Desktop, the update was just completed. Please close your software and reopen it and complete the software updates. You can then go back to your TP128 and verify your calculations.

Thank you for choosing TurboTax.

If you are using TurboTax Desktop, please update it. All TTD forms are available except for the TP-726.7.

The TurboTax Online (DIY) version has also been updated, with the exception of form TP-726.7.

We appreciate your patience as we worked on this.

As originator of this thread, I confirm that the latest update did indeed fix the errors I reported in form TP128.  Thank you!

Let me know when the form TP-726.7 will be unlocked because I cannot print my tax forms until then. This form is a widely used form and must be a problem for many users.

@David_Lavallee, Yes, we will update the locked form link and will also post an update here in this thread once the form has been updated. We appreciate your patience while we work to finalize this form. Thanks

@TurboTaxAniqua There are still errors in TP-128 after the update. I have the most up-to-date version.

Specifically, expenses in lines 210, 212 and 230 get auto-multiplied, apparently by my 50% ownership, instead of the Personal %, even though I already took it into account before entering expenses in EasyStep/T776. i.e. Turbotax inserts phantom amounts into TP-128 column B when it shouldn't.
