We have an intersection of two very different effects.
Agricultural import laws
This is an area of law that normally, consumers have no reason to deal with. However the laws apply to absolutely everyone connected with import of biological items like this.
Of course a recipient of unsolicited seeds has no reason to have learned any of this.
What scientists and lawmakers are worried about is very serious. But of course it's all technical and scientific arcana: there's no reason for a consumer to need to know if they're doing normal consumer things. If you are curious, have an open mind and are willing to ask earnestly, you will find there are very good policy reasons for it, and failure to follow the laws will potentially do a staggering amount of property damage.
Your best bet is to contact your state's department of agriculture or the USDA, and ask them what to do with the seeds. Absent any other advice, I would biologically destroy them by tossing them into any red medical "sharps container" or other bio-waste container at a drugstore, testing lab, free clinic, doctor's office or hospital that you happen to be visiting. Those are incinerated to bio-waste standards.
Brushing - fake review scamming
The usual reason for unordered goods from China is called "brushing" - it is the writing of fake reviews on sale sites - getting a collection of positive reviews is worth a lot of money to the scammer. In particular Amazon is targeted, because the vast majority of products on Amazon are actually from third party sellers, sold through their eBay-like "Amazon Marketplace", which is intermixed with actual Amazon items. Amazon very actively uses algorithms to hunt down and exterminate these fake reviews, so scam sellers go to equally sophisticated extremes to evade that algorithm detection.
Typically a scam seller creates an Amazon product listing for a product intended to be sold. Then, the scammer uses a bunch of sock-puppet Amazon accounts, to make actual purchases of those products with real money (85% of which they get back, since they are the seller). To guard against this, Amazon wants to see proof of actual shipment. So either they stock the item into Amazon's warehouse, or they direct-ship with a trackable method such as USPS's ePacket service, and pass the tracking info to Amazon.
For that, they need a random variety of real US addresses. Nothing easier; in the U.S. real estate ownership data is public record. They haven't hacked you or obtained your PII; they are simply picking random residential street addresses and using those public records to get the homeowner's name. Amazon has access to that same database, so they could detect wholesale use of fake names.
So, random people randomly get packages from overseas or Amazon fulfillment. A fake review is written in your name, but other than that, they don't have your email address or any other PII. It's not a threat to your security.
Now if your name is not in public real estate records, then you might have a problem - but it could be a simple as the hack several years ago of one of the credit reporting agencies.
