How can I find a total of all interest paid last year?

Doing my taxes and need a total of all credit card interest charges. I've downloaded a transaction history report but it doesn't list anything for interest paid on my purchases through PP credit.

I'm trying to find the same info.  The website is NO HELP whatsoever.  Hopefully a phone call tomorrow will help 😞
