Thanks to Mike9241 and DavidD66 both for the information provided. It appears that the cleanest way to fix the problem is to fill out a Form 3115 and recoup the depreciation from all 4 items involved at one time. That means dealing with that form, and I've got to look at it in more detail before doing anything. All 4 items are considered "F - rental furnishings" on the asset worksheets. I used them in "property acquired to earn income as rental property" as a sideline, not property acquired as part of a business organized to provide rental properties, so they are now excluded from the Section 179 option. Their estimated life for standard depreciation would be 5 years, or I could opt for Special Depreciation Allowance, I guess.
