Some of the tax estimators, and even the TTX software itself, will include the stimulus payment right from the beginning...so the Refund shown includes the stimulus payments....until you tell it how much you already received...then it takes away that amount.
So if the shown refund seems too low this year, it would have to be due to something else either not entered correctly/completely....or if it's shown in a estimator APP...those are pretty basic and cannot take all situations into account......so it's a "crude estimate" only.
