You can deduct the home mortgage interest and real estate taxes that you actually paid even if your name is not on the 1098.
In Turbo Tax, you can indicate that "Someone who isn't my spose co-owns this loan, and we only pay a portion of it" and "Neither my Social Security number nor my spouse’s is on the 1098, but at least one of us is liable for this loan" (See below).
If you do not have the information from the 1098, you will have to wait until you determine the correct amounts to claim the deductions.
