I agree about the denial. I use TurboTax Deluxe - Mac desktop version. I've had the same problem and have called Turbotax support 3 times now. They just create and "ticket" and then say to wait for an update. Annette's responses keep saying the program is working the way it should, but she's not addressing the fact that there is NO PLACE in the interview that is titled "Business Conducted in Home Office" and asks for the percentage of time you spend, so you can't enter the percentage that way. The ONLY way is to go to form 8829 page 2 and put 100% in line 8, as numerous people here have mentioned. This made a difference of $400.00 in tax I owed to the IRS! I almost gave up trying to figure it out and am so glad I found this discussion so other users could tell us how to fix it. TurboTax certainly wasn't helpful at all, and that's just not right.
