If you haven't gotten things working yet...
If you are in TWRP, try the WIPE -> SD Card option to get your storage space reformatted. You can then use the MOUNT button in TWRP and it should show up on your Windows desktop again.
Then to get rid of TWRP altogether, you can download the software update from Amazon...
Rather than follow the instructions on that page, rename the downloaded file to "update.zip" (without the quotes). You'll get a warning about file extensions... it's OK to change the name anyway. The file icon will change to a zippered folder after this. Copy the update.zip file over to your Kindle Fire.
Back in TWRP, hit the INSTALL button. Over in the right panel, you should see the update.zip file you transferred to the Kindle Fire. Touch that file name and you'll be able to continue installing that file onto your Kindle Fire. When it's done, you can reboot from the home menu.
It will take a few minutes for it to boot up for the first time, but when it's done, you should have a fresh, completely stock sytem and you'll be rid of TWRP.
