why is line 47 on the schedule D worksheet changing the amount I had on line 46?

[joe7230]

I recorded the sale of a rental property on the 4797(the land in Part 1 and the building in Part 2).  Line 46 of the Capital Gains worksheet has $11829 for total tax to bring to the 1040.  Line 47 changed this amount

to $1074.  I can't figure out why this happens.
