Without the full journey history from TfL I'm guessing. But judging by the touch times on that list, I would say that you have exceeded the maximum journey time at least once, if not more.
For example, the maximum journey time for a zone one journey is either 90 or 100 minutes Monday to Saturday, or 110 minutes on a Sunday. On your screenshot, the time difference between the touches at Waterloo and Victoria looks to be 109 minutes.

Set up an account with TfL and register the actual card which sits behind your Google Pay. This should tell you what you need to know and you can then contact TfL to ask them for a refund. If you explain what you did they're normally pretty good.
It's worth remembering, too, that journeys can be linked together through what's called an 'out of station interchange' (OSI). This means you can touch out at one station and touch in at the next and the system will link the two journeys together.
For this reason, if you're doing track bashing and spending a lot of time inside the system, you are always better off with a paper ticket.
