When I winterized I poured some antifreeze down the toilet but I don't think I pumped any into the toilet should I have flushed the toilet until antifreeze came out? Might have done that but now I'm not sure? Luck I don't think it's been cold enough to freeze yet

Yes! You need to run some antifreeze through the toilet to prevent it from freezing. You need to flush antifreeze through all the lines, including the showers in the bathroom and outside shower if you have one.
Hopefully, you don't have any damage yet.
Kate, the problem with the toilet and freezing is the water valve. It freezes, it breaks. You need to run RV anti-freeze or air through the valve. Fortunately if it breaks it's not an expensive part to replace, about $25. But, I understand it's a real PITA to work on.

Toilet valve replacement cost us more than $100 at a shop and they removed the toilet. Doing it without removing the toilet is not that easy but people have done it. A shop just removes it as they are used to broken toilet valves. Said they saw hundreds where we went.
