Galaxy Tablet Help

I was intending to put Lineageos in my Galaxy Tab S6 Lite (US wifi). There is no version of TWRP for the lite model so I installed TWRP for the standard Tab S6 using Odin. Now the tablet will only turn on when plugged in but it seems that my computer no longer recognizes it. It will boot into download mode but I haven’t been able to figure out how to get any software loaded using either Odin or Heimdall. I’d be fine just flashing the stock software back at this point. Help!
