If you have more entries you will have to print the form and add the extra lines and mail it to CRA:
https://www.canada.ca/en/revenue-agency/corporate/contact-information/where-mail-your-paper-t1-retur...
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
