Yes, I get that and it's fine, I just don't know where in the additions to PUT it.
Why would you ADD it anywhere?
The amount in box 1a is the total ordinary dividends. If that amount is showing up on your state tax return, you are reporting and paying tax on your total dividends.
The amount in box 1b is qualified dividends, a subset of the total dividends. It is broken out since they may qualified for favorable tax treatment. But again, they are already included in the total reported in box 1a. They are not in addition to that amount.
So can you explain more about why you think you need to add them?
Do your state returns not start from the federal totals?
