Thanks for replying!  I manually calculated the business portion and it is the same as the worksheet line 10 - always seems to be the same each time I do this.  In order to get my $1,200 business portion onto 8829 line 17a I enter it on screen 29 unser direct excess real estate. That part seems ok.  Now it seems pretty obvious that I need to enter the personal portion directly on schedule A because Lacerte doesn't know about it since I took it out of the indirect section.  Too bad Lacerte isn't programmed so we wouldn't have to split it out ourselves.

The personal portion pushes them over the $10,000 limit but if I don't enter it myself, Lacerte gives the message  "Since this return is not claiming itemized deduction, you must check the box to allocate morgage interest, taxes, etc when claiming the standard deduction."
