2022 California From 541 states filed electronically, but not true

I printed my 2022 CA Form 541 for mailing with a small balance due.  However the instructions state the following:

"Do not mail a paper copy of your tax return. Since you filed electronically, the Franchise Tax Board already has your return....Your return shows a balance due of $xx.xx. Mail your completed Form
FTB 3843 with included payment of $xx.xx made payable to State of California by April 18, 2023. "

 

I want to mail the Form 541 with a check. What happened?

Thank you.
