How do you reflect on Form 8582, Part 1, Line 1c, "Prior years' unallowed losses", a Sch E residential rental that was off the market for the current one year? To omit the rental for Sch E when you seelect option 1 = "delete this year", it also deletes the prior year unallowed losses from the form 8582. But in the next year the property was rented out again. What is the proper treatment?
