Form 8829 is only for Schedule C, but it can be used as worksheet for other office deductions (Schedule F, Schedule E, Partnership K-1, etc.). After filling it out as a worksheet, you can enter the actual deduction on the appropriate Schedule.
If you want to know whether or not your software has as the ability to use a Worksheet-8829, you would need to tell us what software you use. Otherwise, just print out your current 8829, then delete it and put the deduction somewhere on Schedule F.
There's an interesting story behnd that. In 2007, the National Taxpayer Advocate held a forum in Omaha (across the river from Iowa, a farm state whose Senator Grassley was a Big Kahuna on the Senate Finance Committee. Someone asked why there was not a line on Schedule F for office in home, like there is on Schedule C. She thought that was a great idea, called back to Washington and in a couple days get the forms branch to agree to the change. She bragged about the fast action at the next forum she held, in Phoenix. When the promised line never appeared, I asked several times what happened. Eventually I got the answer that it was decided (by someone) that the line was not needed after all.
