Amend CA State Return

I just e-filed my taxes a few days ago. It was accepted by both Federal and State. I was a partial CA resident, moving out of CA to TX mid 2025. I just realized I made an error calculating my W2 income as a CA resident (January to mid July). I summed up my gross income when I should've subtracted X dollar from gross income for 401k contribution (because 401k contribution isn't taxed until later). As a result I over reported my income by about $12K.

 

In addition to that, I completely forgot to include wife's W2. She had a part time job in CA but quit her job before we moved out of CA. I'm supposed to report her W2 but didn't do it at all. I just realized that today.

 

I have scheduled payment (I owe state tax) on March 3, 2026 (thru bank account direct withdrawal). Can I stop that payment until I correct my state tax and resubmit it? I'm trying to avoid paying CA FTB twice if both payments go through.

 

How do I amend my CA state return? I'm using Turbotax Deluxe on Windows 11.
