@DaveF1006 I called TurboTax to find out how to resolve the error:
Your amended federal tax return was rejected and needs to be resubmitted.
F1040X-016 - For each dependent in 'DependentDetail' on Form 1040-X, there must be a corresponding entry in the same position in 'DependentDetail' on the amended Form 1040 with the same 'DependentFirstNm' and 'DependentLastNm' and 'DependentNameControlTxt' and 'IdentityProtectionPIN' and ( 'DependentSSN' or 'DiedLiteralCd') and 'DependentRelationshipCd' and ( 'EligibleForChildTaxCreditInd' or 'EligibleForODCInd' ).
TurboTax says in the email:
Once you've opened your return in TurboTax, the details about what needs updating will be displayed. From there we can walk you through making the updates you need and help you e-file your return. If it isn't possible to e-file your updated return, we'll make sure you have everything you need to print and file your tax return by mail.
But when I open my TurboTax return there were no directions as to how to revise this issue. No errors show in Turbotax. I have the desktop version.
