It is both the transiting sun and moon. I suppose that was present in everybody’s chart yesterday?
The sun and moon were transiting everyone's chart yesterday, if that's what you mean. They always are. What I meant by a transit to someone's chart was the usual use of that term: a transit to their sun, and/or to their moon. That means something is forming an aspect to their natal sun--or their natal moon--even if the actual sun or moon is somewhere else in the zodiac at the moment.
If you had a moon opposition sun transit to your natal chart during the eclipse, that means your natal sun is at 0 degrees Aquarius (and if it is, that means the eclipse happened on your birthday). If your natal sun is not at the beginning of Aquarius, it wasn't a moon opposition sun transit to your chart. However, if you have any placements in square, trine, or sextile to the beginning of Aquarius and/or Leo, the eclipse made an aspect to those placements.
