I think the va paid me too much, is there a hotline 4 this?

It happens from time to time, sure. Best thing to do is to put that check into a separate account (Preferably one that earns good interest!) along with any other money you suspect might have been over-paid. That way, if the VA comes asking for it back in 6 months (Which, if they overpaid you, they will eventually, guaranteed) you still have it, but you can bank whatever interest it has accrued for you.
