What number should I put as Passive Operating Loss in Schedule E Worksheet?

My rental house has a loss, rather than profit. After I filled up the return online, the Review section said that the Passive Operating Loss in Schedule E Worksheet is missing. What number should I put there? I have used TurboTax online for many years and also had rental loss several years, but have never been asked for that before. I tried to put in last year's carryover number (from last year's Form 8582, Part VII column c) or the number of current year's loss, but it did not help - The Review still asks me to check the same issue. Is this a bug in the program? Does someone know what I should do? Thanks!
