If your your sister filed her tax return claiming you as a dependent, and you filed your tax return and indicated that you could not be claimed as a dependent on someone else's return, the IRS will contact both of you to determine if she was eligible to claim you as a dependent or not. It's not a problem, the IRS will just want to get things right. One of you will probably owe additional tax. Since you filed a paper return it might take a while before you hear from the IRS.
If you do not qualify as your sister's dependent, she should file an amended return to remove you as a dependent. That would resolve the issue.
