I ran into this exact same problem. It only asks if you rolled over to another Coverdell, not a QTP.
At the end of the day, I say I rolled it over to another Coverdell ESA. Turbotax Home & Business appears to not give the option to say a 529 plan.
Hoping it's not an issue as I had to pull the Coverdell money because I wasn't allowed to contribute (income limits) and now I'm telling turbotax I rolled it back into a Coverdell which would not be allowed! (Which isn't actually true, I rolled it within 60 days to a 529).
