Home property taxes being double counted??

[lzo]

Hi -

Typically I enter the info from my Form 1098 in the personal deduction section.

This last year I started a business, so going through the 'home office' deduction.  It says to enter the Real Estate Taxes (which I did).  However, when I go back to the personal deduction section (out of the business section), it shows (see attached) that the $3992 is paid on the principal residence, and again as part of the 1098. 

Appears like it's double dipping?  I can't imagine it should show both.

It does show a deduction for the home office of $348.

So is this correct?  Or should I not enter in the home office deduction (in the business deductions section) and leave it only at the mortgage, interest, and finance section of the individual deduction?

Do not enter your Form 1098 information in the Personal section of the TurboTax interview. Enter that information only in the Business section, as it appears you successfully did, when working on your home office deduction.

Based on your inputs, TurboTax will correctly determine the percentage of use for the home office, charge the proportionate amount of mortgage interest, property tax, insurance, and utilities to the home office, and transfer the remainder of the mortgage interest and property tax to your itemized deductions on Schedule A.

If the mortgage interest and property tax from Form 1098 have also been entered in the Personal section, there will be a double counting of those deductions. This may be remedied by returning to the Personal section of the interview, choosing "I'll choose what I work on," clicking the Update button next to "Mortgage Interest, Refinancing, and Insurance," locating the Form 1098, and clicking Delete.

TT seems to be instructing me to enter my total 2019 property taxes paid both as an expense for the entire home and on the page where you enter expenses for just the home office. Is that correct? It makes a big difference in the amount due.

I'm less pleased.  It worked to delete the taxes from the 1098 form, but this is not at all intuitive.  In fact, the 1098 data entry page has to include a notice instructing the user to not enter an amount for tax if one is entered for a home office.  Yet if the user completes the 1098 data entry first, Turbo Tax should know enough to make the necessary adjustment when the user enters the same data when later visiting the home office data entry screens.

This makes no sense as form 1098 is deductible on your federal taxes, but the home office deduction is not (for w2 workers) but is deductible on your California state taxes. We need to be able to enter both and have TurboTax recognize that the 1098 contains property taxes on your main property
