Schedule 3 warning on filing

[ANCIENTUSER1]

On Schedule 3, indicate if you disposed of a property that was owned for less than 365 days.

I received the same error when NETFILING, used one of the users advice went to Schedule 3 and said No to the question if I sold the property within less than 365 days.... and the Warning went away..., I had to do it for both myself and my husband

I was concerned a lot since neither of us has any Tax slip T3 or T5 

Thank you from the bottom of our heart to the user who suggested that !!!!
