Are you asking about a 760PY and a 763? If so, I do not know of a way to do this easily in ProSeries, so I'd recommend efiling the 760PY, wait for the ack, make a copy of the data file and then change your input to print and paper file a 763. Do you have tax on both returns? Most often when I see this, the 763 "income" is actually suspended passive rental losses so I don't bother. But you could have VA source income during the non-residency period and VA Tax wants you to file two returns.
I can't think of a situation where you'd file both a 760 and a 763 for the same taxpayer in the same year. How can they be both a resident and a non-resident?
