How to Best Store Historical Shopping Cart Data - mysql

Question

I am having a issue with a MySQL table design. Originally, this data comes from a JSON dataset that records all items that a customer as added into their cart along with other information. My problem is figuring out how I should store this data. The goal is to be able to query all parts that a user has added and compare it to the final cart contents to see what items have been added and removed. This may also be a query solvable problem but I am fairly new to MySQL.
Also, this data needs to be in MySQL.
Thanks for any help!
Here is a small example of my parts table:
Here is an example of the JSON, The file is arounf 1 gb so it is a bit hard to find a good example that I can fit in the question.
