@Jane63 thanks for all that information.... there are two areas that I suggest you review closer.
1) I wonder if the problem is how the Excess Advance Premium was calculated. Can you please review Form 1095-A and ensure it was correctly entered into Turbo Tax. The IRS gets their information from the MarketPlace and I've seen examples where that is not working perfectly. What is entered from Form 1095-A should display on Form 8962.
Did you have Marketplace medical insurance all year? did you add or subtract it mid year? was there anything strange about it? Can you go back to your account at the Marketplace and be sure what they now have on file for form 1095A is what you entered into TurboTax?
2) the other problem may be what you entered on Line 25a. Can you please go back to each and every W-2 and be sure that what is in Box 2 on each form summarizes to what is show on Line 25a? if you overstated what was in Box 2, then that would have overstated Line 25a and meant you owed more.
the tax itself on Line 16 doesn't appear to be the problem. In the tax tables, $3332 is for someone with around $29400 of ordinary income so you must have had about $10,000 of capital gains / dividends. Does that fit you?
does any of this help?
