Most of my imported transactions show a payee of "Terminal". I can change these but I need to go to my bank website and look at it to know who the Payee is. Is this how it is supposed to be or do I have to adjust a setting for the Payee to show up.
If that's what your bank is sending, Q can do nothing about it.
Your best bet is to input the transactions manually, before they download, so that you'll get the info you want.
You MIGHT, however, inadvertently have a Renaming Rule that's changing these to Terminal … so explore that.
