My wife and I seperated dec 2018, why is it asking for her information on my return? Do I need to obtain her income to finish my claim?

My wife and kids will not be claimed as dependents this year do to the seperation. 

After you file

If you separated or divorced in 2018, the CRA will still require your spouse’s information.
