Thank you for your help.

When entering the adjusted basis on Form 4684 there is nowhere to enter depreciation so the full gain is reported as long term on line 33.

I figured it out. The disposal has to be entered on the enterable 4797 p 2 and the depreciation flows to 4797 line 13 ordinary gain. If there is any additional gain then that portion flows to F 4684 line 33 long term gain.
