In attempting to prepare a superseded tax return for a client, I am getting a diagnostic saying that the change to the deduction for seniors cannot be a negative number. In the previously filed return, my client got the full $6,000 deduction for both the Taxpayer and Spouse. By virtue of amending the return, my client's AGI increased by $24,030 and that in turn caused the senior deduction to be reduced from $12,000 to $11,424 which is a difference of $576 and that is obviously a reduction. But I am getting the following critical diagnostic and can't seem to figure out how to fix it: Form 1040-X: The Net Change for the following item cannot be negative for e-file purposes: Deductions for tips, OT, car loan interest and senior from Schedule 1-A Form 1040. Does anyone know how to clear this diagnostic? Thanks in advance for your help Jerry F. |
