If you can still get into twrp then you haven't wiped everything and its no problem to get it going again. There is an option called mount in twrp, with the device connected to a pc via usb click mount, this allows you to access the internal device storage from the pc and easily transfer a Rom over to it which you can then go back to twrp main menu and install. Always remember to do some research if you don't fully understand what it is you're doing before you do it. Next time you might end up with a brick.
