That was bold turning it on again just a day later! I'd have left if a few days, liquid evaporates more slowly in enclosed units.
FYI this is what a push2 looks like on the inside

The main matrix is handily covered by one big rubber sheet. The side button elements are sealed units, which is handy for wine-proofing. My personal worry would be the encoders, so it depends where on the unit you splashed it.
Wine is sugary and will turn toward the acidic as it oxidises, which isn't that great for delicate components - including that magic rubber sheet..
In the past I spent about 15 years draining idiot punters drinks out of my gear and most of it still works fine, so you are probably OK. But it might be worth popping it open and taking a look for any bad signs (and to make sure its completely dry in there). Opening gear and cleaning it is usually pretty simple, especially with youtube to guide you. So if you feel like getting intimate with your push you could pop it open and take a look around to set your mind at rest.
In fact right this minute I'm cleaning inside my ancient MS20, which was drowned in beer several times and lived in a haze of oily smokemachine fluid.
Still works
