You would report it under Sale of Home. Type Sale of Home in the search bar and then click Jump to...
You will see the screen "Depreciation After May 6, 1997"
This is where you would indicate the Home Office. See below information for the recapture from Pub 523.
If you used all or part of your home for business or rental after May 6, 1997, you may need to pay back (“recapture”) some or all of the depreciation you were entitled to take on your property. “Recapturing” depreciation means you must include it as ordinary income on your tax return.
