Hello,I've just gone to file and it says I have ABP interest adjustment (Schedule B) and need to upgrade to Deluxe. But I don't have any bonds so I don't understand how this applies to me.

Edit your 1099-INT form(s).

Look for entries of any amounts in boxes 11, 12, or 13.   

1)  IF you have real values in any of those boxes, then you do have it.......then check your paper forms for a mistake...perhaps they need to be deleted if they truly do not exist.
...OR....
2) IF you have a 0.00 in any of those same boxes, don't leave them alone....delete any 0.00 in those boxes so that the box is empty.   This one could be the problem.
