There isn't an option to fill in box 10 on form 1098

[Vanessa A · Accepted solution]

Box 10 on your 1098 is Real Estate Taxes paid.  If you have an amount in your box 10, you will just need to enter it beneath box 5 in the box labeled Property (real estate) taxes

Box 10 on a 1098 is informational. TurboTax can not do anything with it.  If it affects your tax return, and it usually doesn't, you have to make manual adjustments.
