I am sorry, I am quite new to this, so my terminology may have been incorrect. I did not file a tax return, but I submitted the W-9 that the employer requested. On the W-9 in line 3, stating,
"Check appropriate box for federal tax classification of the person whose name is entered on line 1. Check only one of the following seven boxes."
Here, I selected individual, as in "Individual/sole proprietor or single-member LLC"
I know for a fact that I am claimed as a dependent on my parent's tax forms, but I don't know if that has something to do with why my w-9 was rejected... does it?
