The new software ALWAYS uses the previous year's numbers until AT LEAST mid-December. 

That is because Intuit does not use official tax guidance, such as the IRC, Regulations, Revenue Procedures, etc.  They use the the not-to-be-relied-on Publications and Instructions.  So until the IRS finalizes the Publications and Instructions, Intuit does not update the software, which makes the software pretty much useless for the first month or two.
