Just wanted to add one thing that I tried. In Review Check for each home office, I took each amount based on percentage of use (a1, a2), added them together (c) and found they did not equal the number Review Check said should be the sum of both (d=a1+a2). So I calculated the difference (d-c) and then took the percentages of these amounts based on use to produce two "supplemental" amounts (b1, b2), then added each to total expenses for each home office, as in: d1 = a1+b1 for one home office (total expenses) and d2= a2+b2. When d1 and d2 are added together, we hit the number Review Check wants us to hit. So I enter these new numbers in the Review Check boxes for expenses related to each home office (d1 and d2). Upon redoing the Review Check the problem goes away, but here's the thing; those numbers have NO bearing on the actual numbers sitting in Schedule C for each home office. Schedule C contains only the originally derived numbers (a1, a2) from the worksheets/step-by-step. So the Review Check "works" but the numbers are off in the actual Schedule C. I do not feel comfortable about just arbitrarily putting in numbers to satisfy Review Check that are not connected to the actual expenses related to each home office in Schedule C.
