Family HSA

Me and my wife are over 55 and have a high deductible family plan.  I contributed $5385 to our HSA this year.  I answered all the questions correctly but tubotax said i over paid my hsa and doesn't take in account the family plan that allows like $7750 for me and my wife.  turbotax wants to tax me on the excess of $2,020.  The program is wrong and needs to be corrected.
