How do I have Turbo Tax to auto fill the carry overs from last years return to the current return?

I am working on my tax return.  I am trying to work on foreign income credit carry over.  Turbo Tax did not update the 1066 Schedule B with the numbers from last year.  How do I proceed?  If I have leftovers from last year to carry over, how do Iadd them?  This year's TurboTax gives me a 1166 Comp Wks, instead of 1166 Schedule B.  It gives me 4 columns for each prior year (a) Foreign Taxes, (b) Adjustments, (c) Utilized, (d) Carryover.  Last year's 1166 Schedule B has 5 years worth of carry overs, last year and 4 previous ones.  How do I proceed?  What is the max carryover I can claim?  Do I adjust until I am satisfied with the amount shown on my Fed return?  Thank you.
