Should I ignore the Review: Warning that I should have entered my UCCB payments received? It's coming up for a FY2017 return and makes no sense as UCCB no longer exists.

This error message looks like it was carried over inadvertently from the 2016 tax year and should be deleted.

Troubleshooting

If you did not receive the Universal Child Care Benefit in the year 2017, it does not need to be reported on your 2017 income tax return.  However, you may want to check with the Canada Revenue Agency to be sure that they do not have an RC62 on file for you.
