Federal tax return showing as 'not signed' in college financial aid portal

I think the confusion is that the digital signature (final page of the turbo tax) when you send your taxes is usually a digital number, not “signed name”, which is what the school needs on the tax forms. It has been my experience that some schools have sent the documents back asking for a signature. Students took the forms home, I scanned them and sent them back to the schools (with no further problems)
