Schedule B has an entry "accrued interest paid" that is the exact amount of money that I entered as interest received. Where did this come from?

Because of this accrued interest paid entry, Schedule B reports double my interest income.  I can't figure out where this comes from or why it would be exactly the same as the interest I received.  This shows up on the PDF of my return, but I can't find it in TurboTax.
