When preparing a dual-status return, how do I account for the tax due from the dual-status statement?

For example, I have a client who started as NRA and then got a green card in October.  I'm preparing 1040NR for Jan - Sep, and then 1040 from Oct - Dec.  1040NR is statement, and 1040 is return.

If there is money owed on the 1040NR statement, how do I add to the 1040 return?  Is there a particular line or schedule to enter the amount due from the 1040NR?
