I could not get the e-mail service request to work. But I called and talked to  customer service. The person is not a tax specialist but we spent some time trying to figure out why it is calculating that way. One thing we noticed is that in the partner basis worksheet there is a place to enter "Business interest expense included in current year income or gain" which is new this year. An entry here would have seemed to enable me to make the basis correct but it did not go anywhere on the basis worksheet. However when I entered all the basis information manually (without any special entry for the interest expense) to the worksheet I get the correct basis even though the partners share if interest expense still shows up on line 4b of the worksheet.

The service rep is going to check on this and give me a call.

I suspect this is a software issue that needs to be addressed. I was not speaking with a software expert.

I will keep you posted.

I would be interested to know if anyone else has had this issue. I would think so unless no one else keeps track of basis.
