How can I change my selection on an answer if it is greyed out?

[vweis]

When reviewing my return forms, I accidentally clicked 'single' instead of 'married filing jointly' when it asked about my parent's filing status (I am a dependent). How do I change my answer? it wont let me click anything else on the page; everything is greyed out.
