[JohnW152]

First, you don't necessarily need your parents' actual return, but you do need information from it.  See 2020 Instructions for Form FTB 3800 for more information.

And, second, if you're filing your tax year 2020 return, you need information from your parents' 2020 return, which they may not have prepared yet.
