Accessing last year when this year already completed

[Vivsim]

I have completed my 2020 return, but I neglected to populate it from my 2019 return at the beginning.

I would like to produce a detailed tax summary with both years side-by-side.

I there a way to accomplish this?

Unfortunately, if you didn't transfer your info from your last year's return into your current year return when you started, there is no way to do so afterwards. You will not have the year over year comparison available.
