Hi, thank you for using Intuit ProFile Community
There should be no issue completing date and time on a T183 before the return is e-filed. If you filed before those entries were made, try unchecking CRA errors in properties before making the T183 entries. If that does not work save the return then select form > clear form, while the T183 is displayed on the screen.
It is important that this works: if you continue to have issues making entries on the T183 call us at 1-800-452-9970 for an agent to investigate.
I apologize for the inconvenience but hope this helps
