I have the same problem; I received an IND-996 rejection notice. Where do I enter or delete the "Dep IP PIN", in which form? I search my return and there are only two IP PIN fields (which have always been blank) on our married-filing-jointly tax returns. You mentioned a worksheet - I thought worksheets were not included in the tax returns, so how do they obtain the "Dep IP PIN" information, which is the reason for the rejection IND-996? Thanks in advance for your answer.
