Is it normal to not have received your Maryland refund 2 weeks after getting Federal refund?

[ErinH]

Yes. Your state and federal returns are processed by two separate government entitites. Your federal return is processed by the IRS. Your state return is processed by your state's Department of Revenue. One return does not impact the other.
