We're seeing an incorrect Schedule H (doesn't match nanny payroll). Beyond "Other" > "About Your Nanny," where does Sched. H pull from? Where did I enter something wonky?

Our payroll's schedule H lists federal income tax withheld as one (lower) number.
The schedule H that turbotax is generating lists federal income tax withheld as another (higher) number.
(The difference is 1,384, not a number I see anywhere else on our documentation!)
