Deductions & credits

A.  I don't know, because I can't see the amount on line 18 of form 1040 till I complete the return (unless Turbotax offers some kind of preview, which is not evident).

B.  Ditto, I can't see a preview of form 1116 filled in; Turbotax offers only the walk-through without IRS line numbers.  Looking at a blank specimen of 1116, my line 14 should have a positive amount, as I paid plenty in foreign taxes, and duly entered that on Turbotax's walk-through of form 1116.

Please offer further advice.  I'm at 20 hours now without success.  What a nightmare.
