If I received a filing extension through Turbo Tax Easy Extension, do I have to file my return with Turbo Tax for it to be effective or can I submit a paper return?

As a nonresident alien some forms I need are not available through Turbo Tax. Therefore, I have to file a paper return. However, I requested an extension using Turbo Tax because of an error on my W-2. Will the extension I obtained through Turbo Tax still be effective if I do a paper filing?
