Belasting

I don't find a Box 17. I fill in an online tax return, which asks me when tailoring my return if I receive property income more than £1,000. I find no other obvious place to enter this income and the taxes already paid on it. Help.

I have holdings in three REITS listed on the LSE. I was paid dividends of less than £1,000. I have had tax deducted. How do I list this income and the taxes already paid on my self-assessment?
