How do I keep track of mortgage interest received?

Joe7

I have a loan set up on Q with myself as the lender. When I look at the payment details, I see the breakdown each month for Principal and interest, but if I run a report for any of the interest income categories, it's not showing the mortgage interest received.
When setting up the loan, I do not see anywhere for me to create a special income category. Please advise, Thank you.

What category is defined in the transaction Split detail for the Interest amount?

When you originally created the loan that category may have been defined as an Expense category, e.g., Loan:Interest. After that, when you converted the loan to a Lender Loan ... did the category change to an Income category or is it still an Expense?
