I haven't got my tax returns yet. It was my first time having a job so its not like I owed money. How do I check on the progess of my tax returns?

If you filed your 2007 tax return and have a refund, you can check the status of your refund at the IRS web site.
If tax was due and you attached the check with your tax return, then check your bank statement.
It no tax was due and there was no refund, then you will not hear from IRS unless IRS finds a correction.
