That's OK.  You can report your mortgage interest just as if you had been issued a 1098.

1. Click on Federal Taxes > Deductions & Credits  [In TT Self-Employed:  Personal > Deductions & Credits > I'll choose what I work on]
   
2. In the Your Home section, click on the Start/Revisit box next to Mortgage Interest, Refinancing, and Insurance.  [See Screenshot #1, below.)
3. Continue to the screen, Let's get the details from your 1098 now.  Enter the information on mortgage interest, mortgage insurance and real estate taxes (if you haven't reported them elsewhere).  [Screenshot #2]
