do I have to type all this in again?

You should upload your return from the prior year before you start.  Did you log in to the same account that you used last year or did you use the desktop program for this year's return?  Either way you should use last year's return to start and then you don't have to re-enter any of the same information that you typed in then.  Delete what you have entered and start over.
