Can I get a copy of 1040 form based on my estimates so I can turn it in to my son's school for financial aid calculation? They need it before I have all info.

I do not receive all information from investments until after the due date for financial aid application.  The financial aid office is fine with me using last years numbers for dividends and interest.  They want me to turn in an estimated 1040 based on this years income and last year's interest and dividends.  Is it possible to access this year's 1040 from Turbo Tax before officially filing so I can turn this in to the financial aid office?
