Most likely the IRS reduced your refund, so SBTPG did not receive the amount shown on your tax return. The IRS might have reduced your refund because you owe back federal tax, or because they found an error in your tax return. (Past-due federal tax is not an offset.) The IRS will send you a letter explaining why they reduced your refund. The letter usually comes two to three weeks after you get the refund. See the following links for more information.
