Sometimes I've had to delete the PY Alloc Wks and start over.  Don't know how much data you have in there but if it's just a few entries you might try:

1) Use the W-2 Wks for the wage allocations

2) Delete the PY Alloc Wks

3) It should immediately and automatically created a new PY Alloc Wks based on your entries in the Fed Info Wks showing PY state info

4) Cross your fingers and see if there are still errors in wages . . .
