Question about county tax in state income tax returns

[Juche]

I am in Indiana, and left college in summer of 2007, then found a job in April 2008. On my state tax return it asks for the 2 digit code for the county I was employed in on January 1st 2008. However I was unemployed at the time. So do I leave that area blank, put in my county of residence (where I was unemployed) or what exactly?

I tried calling the tax helpline but they are closed for the weekend, and I am not finding anything on the indiana tax website. So I figure someone here might have an idea.

1. I found this on the Indiana tax instructions

Look on page 25. It defines the county where you lived and county where you worked.

County where you lived defined
The county where you lived is the county where you maintained your
home on Jan. 1, 2008. If you had more than one home in Indiana on
this date, then your county of residence as of Jan. 1, 2008, was:
Where you were registered to vote. If this did not apply, then your
county of residence was
Where your personal automobile was registered. If this did not
apply, then your county of residence was
Where you spent the majority of your time in Indiana during 2008.
Did you move during the year?
If you moved to another Indiana county after Jan. 1, 2008, the county
where you lived for tax purposes will not change until next year.
If, on Jan. 1, 2008, you lived in a county that has a tax, then you will
owe county tax on all of your Indiana adjusted gross income.
If, on Jan. 1, 2008, you lived in a county that doesn’t have a tax,
then county tax will be figured on your income from your principal
employment if the county where you worked on Jan. 1, 2008, has a tax
(see definition below).
County where you worked defined
The county where you worked (county of principal employment) is
the county where your main place of business was located or where
your main work activity was performed on Jan. 1, 2008. If you began
working in another county after Jan. 1, 2008, the county where you
worked for tax purposes will not change until next year.
Example. Jessie worked in Marion County on Jan. 1, 2008. She quit that
job and began a new one in Johnson County on Feb. 10, 2008. She will
enter the Marion County two-digit code (49) as the county where she
worked even though she changed jobs during the year.
If you had more than one job on Jan. 1, 2008, your principal place of
employment is the job where you worked the most hours and earned
the most income.

2. Thanks for looking that up

I appreciate you taking the effort, however I found that info in the booklet yesterday and am still confused. I wasn't employed before 2008, and I was unemployed (ie a college student) in January 1 2007.

So I still am not sure what to do.

3. If you can, just put 'N/A' in the box. Not Applicable.
