Thank you for the insight. I came to the same conclusion i.e. if I do not include the addition contribution in box 16A then the problem seems to go away. The problem with this approach is that instead of getting a small refund I get a small amount owed. Conclusion: after more than 10 years of using TurboTax, this was my last. For the moderator: I want to be refunded $45.19 ( cost for the De Luxe package purchased at Staples)
