If you don't itemize then it's usually not going to make a big difference. Also, you should get a different tax preparer if that is what they are doing. I've rated Foster and Company before in this venue and I'll tell you that you really need to work with a firm that will EXPLAIN the tax issues to you so you know what to do and what to plan for. Most people don't itemize, particularly if they don't own a home, or depending on their income bracket. Even with 70% of the US population owning homes in some areas the cost of the home's interest annually is too low to qualify a deduction larger than the standard.
Try contacting the folks at Foster and Company for next year's return if you want to get a good response.
