Don't have a warranty and my 512gb SSD partition failed

[BraydenGamelove]

My PC's SSD has messed up and it no longer shows 512 GB. This all started as I decided to reinstall Windows with a custom ISO, specifically Tiny11, I managed to get to the installer with no problems and I chose C: as the drive I wanted to install Tiny11 on, which is the 512 GB SSD with the old stock bloated Windows on it. (and some games which require a certain drive speed, etc) Tiny11 however had other thoughts and somehow It installed on my 1TB HDD even though the drive letter was 😧 and not C: so I'm stuck with a PC with an unusable os because it is installed on a slow drive. And I cant even reinstall because when  I first downloaded it disk manager showed that my SSD was now 2048 GB of unallocated data, which is not the size of the SSD, I used Testdisk to try and fix it because I was recommended it by discord, It read deleted portions with windows on it correctly and showed 512 GB, I selected L on all of them to write them back onto the portion and now I only have 27 GB of storage on the SSD and I can no longer even see the remaining 400gb in Testdisk nor Disk management. 
I also get a short error when booting, it says Abnormal status detected by rapid storage UEFI something. 

I really need help because that drive had many important files and I don't have a warranty or have the money to send it to a repair shop.

@BraydenGamelove , welcome to the Community.

I believe that your best option is to go on the Forums for Tiny11.  They are the experts on their product.  I don't know how many of the members on here even know about Tiny11.  I don't have any knowledge of it.
