Yes you must file a return if you have income that requires a return to be filed. Even if your income is too low to require you to file a return, you should file to get a refund of any federal tax withheld.
You are required to file a return if you had more than $400 of 1099-MISC income in order to pay self employment tax.
If you file, make sure you indicate on your return that you can be claimed by someone else.
