I need help. 

What is interpretation of line 5 d in Sch A: FROM OFFICE IN THE HOME.

The amount I see here is not as same as amount the portion of Real State tax which I manually calculated and put on line 11 as indirect expenses on form 8829 based on the business started(business began around July). I think it is the rest of unused real state tax based on the date business stared during year for example 200 day/365 days. Still when I add portion of home and the amount line 5d in Sch A, I have not the whole amount of real state tax which is on 1098 box 10. How can I add the rest on Sch A?

Also, 8829 instruction says when you want to use standard deduction use line 16&17 on 8829 for mortg and real s tax and use line 10&11 for who want to use SchA . Proseries is not able to calculate portions at both methods. To clear for anyone wants to work on 8829 I think we need to find out what the procedures is when client want to use 8829 and standard deduction or use 8829 and sch A (when SchA is more than standard deduction)
