Enter the date of death as the disposition date on the Asset Entry Worksheet.  Then leave the sale price BLANK.  That will stop the depreciation for the 'old' Basis.

Then add a new Asset Entry Worksheet, using the date of death as the "placed in service" date and the Fair Market Value on the date of death as the Basis.

For any future readers, that process is ONLY for clients that are in a Community Property State.  A non-Community Property State has a bit of a different process.
