This bug or error persists in 2026 for the 2025 tax year. Even though I check the box on the interview that all the business is done from home, the limit calculation on form 8829 line 8 was picking up total expenses Ln 28 not Ln 29 the net income. As a result the program saw a net loss (total expenses) and carried over the home office deduction.
The workaround to put 100% on the 8829 worksheet worked, but is a program error in that the interview didn't automatically put it there. Only after a few hours of time and reading these posts did I finally arrive at a fix. This needs to be corrected.
I'm using the Deluxe desktop version on a Mac.
