There are only a few forms that have still not been finalized yet: https://turbotax.community.intuit.ca/replies/3769141
If you haven’t used any of these forms on your return, double check that you (and your spouse, if you have one) have not accidentally said “YES” to the Tax on Split Income (TOSI) question. Us the Find tool (or the Forms lookup) to search for Tax on Split Income, answer the question “NO” and click “Continue” to save. Then try to file again, starting from the beginning of the Review section.
- From the left side menu, select Review.
- From the options that appear, select Get Started.
- Continue through your return and file.
