"not required" to file might be beside the point. If you worked and had tax withheld from your paychecks, then even if you earned under the limit to be required to file, you would want to file a tax return in order to seek a refund of the amounts in boxes 2 and 17 of your W-2.
If you had even $400 of self-employment income, you are required to file and pay self-employment tax for Social Security and Medicare.
