Transferring tax info

I really wasn't sure how to phrase or ask this, but I was doing my taxes, and I realized I chose the wrong file from last year.  (I did my taxes based on both standardized deduction and itemizing last year).  Is there any way to get the data I have put in (I am almost finished with the federal return), so I don't have to start completely over if I want to use the correct return from last year, so I have all the correct comparisons?

 

Thanks.
