I have no idea how signing for FedEx works, whether or not they actually have to scan the barcode on the package for it to be signed for in the first place, or just pressing the package they're dropping off on their scanner.

To update the tracking details, the package Is scanned at Its destination and (In your case), a signature Is requested.

On the FedEx tracking page for my package, it shows my step dad's signature and the first letter of his name as well as his last name.

Given your dad signed with his real signature, It will significantly complicate the DNA.

Although my stepdad signed for the package, he and I do not have the same last name because my mom remarried. 

It doesn't matter - he's an authorized recipient of the same household.

For the possibility that my mom's package did not require a signature, is it possible to try and claim this was a bug in their system?

It's not convincing, hence It's very unlikely they'll believe It.

Since both packages came at the same time, there may have been the possibility of MY package being mistakenly signed for

By whom?

They were both delivered at the same time, scanned at the same address and signed for by a household member.

So is FTID the only way for this to be refunded? I know the gist of it and that it has many flaws. Nevertheless, I highly doubt DNA will work or how I will even try to pull it off.

Might just resort to trying to find someone to FTID it for me.

If it's not opened yet you could try the sealed box method? There's a much better rate of success than the FTID and doesn't require hiring someone. You able to get the box open perfectly?
If that fails then just return normally and hit somewhere else, imo

The method (If you can call It that) Is flawed, and contains an array of Inconsistencies that predominantly lead to failure.

In the event It somehow does work and you think you're In the clear, there's every chance the company will pick It up as a non-returned shipment later down the track. I don't need to explain what happens next.

I highly doubt DNA will work or how I will even try to pull it off.

Under the circumstances, disregard the DNA.

As @_Kenzo_ mentioned above, the sealed box method Is well suited. Alternatively, the disposed of the faulty Item or the wrong Item received can be used.

wish me luck, attempting disposed of faulty item rn.
