I have two 1098's from a timeshare that I own. Where should these mortgage interests get entered?

Form 1098s are entered under Schedule A.  To get to the correct spot:

1. In TurboTax go to the Federal Section and select Deductions and Credits;
2. Scroll down to Your Home and click on "Start" next to Mortgage Interest and Refinancing (Form 1098)
3. Click on "Add a 1098" and enter the information from the 1098
4. When done with the first 1098 and you get back to the page that says Your 1098 info so far
5. Click on Add Another 1098 and enter the information for the second 1098.
