Antifreeze in Atwood water heater
I accidentally pumped antifreeze into my hot water heater. Can I wait until spring to completely flush it out?

Only real question-- was the water heater full (of potable water) when you started adding potable antifreeze? If so, it could be too diluted to properly protect your system.
Said another way 6-10 gallons of water added to the potable antifreeze changes the freeze point substantially.
This guy is right. If you have by-pass valves for winterization then you should go ahead and pull your anode rod or plug out of the water heater to drain. Otherwise water heater would eventually freeze up because there isn't enough anti=freeze content in that water heater to protect it.
