What if I added a school code on my FAFSA application after the deadline

Hello everyone!
I’ve transferred to California State University and enrolled in 9 units. The school took all of my financial aid (Pell grant) to pay for tuition fees and I also had to pay something from my pocket to cover all tuition fees. When I went to the Financial Aid office to ask why, they told me that I submitted FAFSA application late.
The thing is that I submitted FAFSA application for 2019 - 2020 academic year in fall 2018 (at this time I wasn’t sure exactly when I will be transferring), which is in time, but I added CSU to my FAFSA in fall 2019. Is this considered late submission and I lost part of my awards?
Please, somebody clarify me!!!

Were you supposed to get a Cal Grant?

Fall 2019 would be “late” since you’re attending school in the 2019-2020 school year

It is not too late for a Pell grant. California can set any deadline it wants for Cal aid (but did you have at least one Cal school on your FAFSA before March 2, 2019?)

Did you submit your FAFSA to any CA public universities when you applied in the fall of 2018?

Did you submit it to any Cal States?

Where did you transfer from?
