Drupal 8.x

I have a text list field with these elements
E | Exam
R | Review
T | Technique
I need to delete the line
R | Review
but the system replies that it is used in the Database and it is not possible to delete it.
Is there a way to do this?
I also need to change the Movement Type from R to T
I thought of Filtering the movements with getStorage and then with foreach modify the data

I have 37 fields that I need to have visitors be able to fill out. (lab test results) I can't find information on how to format that node in a way where it isn't a giant laundry list of entry points. I'd love to get them setup in a table or even a grid for the data entry to match up with what the lab results look like.

Very new to Drupal but getting the hang of it pretty fast.

Thanks in advance for any help you can give me.

In the Visualization management of the form I have inserted a field group with expense label and been closed.
Depending on the situation, I would like to open and close the tab and if possible make it invisible.
I have tried this code
$form['#fieldgroups']['group_spese']['format_settings']['formatter'] = 'open';
But I get the error that it is not possible to use it on a standard class but I did not understand how to do it
