You may need to uncheck the box for "error-checking" when e-filing the tax return (you need to e-file from Homebase to do that; you can't do it within the client file).

However, I'm not sure why you want to override.  If it was taken out of service, enter the disposition date and leave the sales price BLANK.  That removes it from service and stops depreciation.

If you want to preserve the Asset Entry Worksheet, enter 0% business use (or 0.01% if 0% gives you an error).
