If you're trying to get rid of an unnecessary Form 8829 (Expenses for Business Use of Your Home) and you're not having luck with manually deleting it, try this:
Open your tax return. (To do this, sign in to TurboTax and select the Take me to my return button.)
Search for home office and select the Jump to link in the search results.
On the Your 2018 self-employed work summary screen, select Edit to the right of your Business Name.
Scroll down to Expenses and select the trash can icon next to Home office. (If you have more than one home office, choose the home office you want to delete.) Confirm by selecting Yes when asked if you are sure you want to delete the form(s).
