updateOrCreate() updating database using index - laravel

Question

I have a submit and update function for my form and in that form, the user can choose to add an additional row of inputs. These inputs will be saved in a new row, basically, one user can have several rows in the database. I have a problem with the update function, where if the user originally has two rows answered, in the update function if they still fill in two rows, both of the rows in the database will be updated, however, only the first row is getting updated. I tried accessing the key for the arrays and updating based on the array keys but it doesn't work.
Here is my whole controller:

I created a variable to store the arrays because I realized that if I simply use the model name and then do updateOrCreate() it will probably only update the first one. But the result of that update function is that it updates the first row in the database, then creates a new row for the additional row, but I want it to update the other rows in the database instead.
For more context, I followed through this tutorial for the adding input fields and saving function. Now I have trouble trying to do the update function.
