Investors & landlords

It seems like every year I have to go digging for answers on RSUs. This is very helpful, thanks Tom. Now, one follow up question - on the same page where I enter the corrected cost basis, it also asks for federal tax withheld and state tax withheld. If I already entered the number of shares withheld to pay taxes, do I also need to enter those amounts here? or would that be duplicative? Is there a problem with leaving all other boxes blank?
