I have a similar question with a small twist. The1099-R form from my state pension system has different amounts in Box 1--Gross distribution and Box 2a--Taxable amount. The taxable amount is less and reflects a small post-tax contribution that is included in the gross distribution and reported in box 5. Which amount should be reported in box 16? Should it be the gross distribution amount (including untaxed distributions) or the taxable amount? The taxable amount for state income tax purposes is the same amount as for federal income tax purposes. So, should I enter the taxable amount in box 16?
