I received dividends from a Canadian bank account that my father holds in trust for myself. How would I claim these funds on my taxes?

Yes - you do have to declare the investment income reported to you on the Canadian Form T5 - Statement of Investment Income. Enter the dividends as if they were reported on a 1099-DIV:

1. Click on Federal > Wages & Income. 
2. Scroll down to the Interest and Dividends section and click on the Start/Revisit box next to Dividends on 1099-DIV.
3. Answer Yes to Did you receive any dividend income? (even though it was not reported on a 1099-DIV)
4. On the next screen, click on I'll type it in myself.
5. Enter the dividend information and continue through the rest of the interview.

Thank you for your reply. How would I enter the amount on the 1099-DIV in Canadian funds? 

You need to convert the Canadian amounts to U.S. dollars and then enter the U.S. dollar amounts in TurboTax.  Use the "taxable amounts" from the form.

You have a choice of which rate to use, so use the one that is most beneficial to you.  Here are some resources for exchange rates.  If given a choice of a date, use December 31, 2021.
