If you have more entries you will have to print the form and add the extra lines and mail it to CRA:

If you want to efile it > you can combine entries in one line to be able to efile the T1153 > this will not drop the requirement of mailing the form after with a letter of explanation.

I hope this was helpful 

Why have you not fixed this. People have been asking for this for years!!

When is TurboTax going to fix this? It is now 2023.
