Found the problem. Need to take the difference between "Amount" (for example $177) and "Reportable Proceeds" (for example $127) to determine original cost of the bond (for example $177 - $127 = $50) and then, since the old fashioned paper bonds had face values of double what they cost, double the $50 to get the face value of $100. Then the amounts on form 8815 will match the amounts reported by TreasuryDirect on Form 1099.
