I am unfamiliar with the form you mention. Presumably the interest is reported in box 13 of a T5. Deductions related to investment income are claimed as carrying charges. Please refer to the following link, and perhaps what you have in your letter from BMO will fit.

Why wasn't the interest received? Presumably you mean you have a T5 showing the interest as your own income.
The IPSRR1 form explains, I quote: " Due to early redemption, The difference of xx.xx which was reported but not received by you, should be claimed as a tax deduction". And actually, the forms starts with "Over the period of 11-SEP- 2015 to 14-SEP-2017, you received xxx.xx in interest..the Bank was required to report on Forms T5"
Hi TurboTaxJeffrey, I want to add that the same question was asked 6 years ago but apparently it was not answered.
